A brazen gang shifted such "eye-watering" amounts of drugs they had to document their trade on spreadsheets.
The Liverpool-based crew moved 170kg of cocaine, 11kg of heroin and 290kg of cannabis, worth more than £8m in total, in the space of just two months.
The crooks were so confident their EncroChat encrypted phones were "impenetrable", they abandoned traditional tick lists in favour of Microsoft Excel.
Liverpool Crown Court today heard how their business grew to such a scale that professionalism was needed and records had to be kept - before it all came crashing down in police raids on September 11 last year.
Stephen McNally, prosecuting, said: "This was not the stuff of tick lists on scraps of paper, this was the stuff of spreadsheets."
The court heard the gang's alleged ringleader, Callum Hogg, aka EncroChat user "SpeedyHerder", remains at large.
But his cousin, the former boxer Ryan Mulcahy, 29, along with Anthony Connolly, 30, Liam Hughes, 24, Hughes' dad Brian Marshall, 46, and Jack Pritchard, 29, today appeared for sentence.
Prosecutors said their operation had international links to Morocco, Spain and Dubai, and connections across the UK to London and Cardiff.
Mulcahy went by the handle "BassBelt", Connolly was "OrdinaryDingo" and Hughes was "BleakMoth". No devices were attributed to Marshall or Pritchard.
The case covered plots from January to September 2020, but the extent of EncroChat data recovered when the secret phone network was hacked was so big that investigators decided to focus on May 10 to June 13.
Referring to the amounts of Class A drugs, Mr McNally said: "The figures involved are quite simply eye-watering."
He added: "The figures that have been reached are not fanciful evaluations or exaggerated extrapolations.
"These are based principally on the group's own data and records, their own conversations and their own admissions.
"Liam Hughes said during interview that he'd been involved in criminality for about six years and at this level for about two years.
"He said that he earned between £4,000 and £8,000 a month and that for about six months prior to his arrest, a bit less than £100,000 cash came through his address every week."
The group used six "slot cars", fitted with bespoke "hides" designed to conceal drugs and cash.
Mr McNally said the hide in a gold Renault Scenic, registered to Marshall and driven by Pritchard to Wales on June 1, had the capacity to hold approximately 15kg of drugs, or £150,000 in cash.
When talking with another Encro user, "NuttyElk", on April 10, Mulcahy boasted: "Man its a proper stash car plod cant find cost 12k"
Mr McNally said: "That is demonstrative of the level of sophistication and also the expense and effort invested into protecting their lucrative business.
"Such was the quality of that installation work in that Renault Scenic, that it was searched on three occasions, before the hidden 'slot' was actually identified."
Connolly, who previously lived in a city centre apartment in Ellerman Road, transported and collected money and drugs on "practically a daily basis".
He also coordinated the "slot" cars and was the "accountant", who kept track of finances and stock on a laptop.
When his home in Station Road, Melling was raided, officers seized the MacBook Pro, along with £670 in cash.
Connolly had sent screenshots of spreadsheets to Hogg and Hughes, which detailed amounts and brands of cocaine supplied and at what price.
The court heard these spreadsheets showed that in May alone the group supplied 64kg of cocaine to customers for £2.2m, received around £925,000, and appeared to bank £745,000.
Mr McNally said largely due to the Covid lockdown, business was described as "quiet".
He said: "The Crown can only imagine the quantities that would have been involved should they have been 'busy'."
Prosecutors said Mulcahy, of Maregreen Road, Kirkdale, sat just below Hogg in terms of a cannabis plot, and coordinated the distribution of this drug, while also directing Connolly in collecting and delivering cash.
Mr McNally said Hughes' home in Karonga Way, Fazakerley, was used as a "safehouse" for large quantities cash and Class A drugs, which were weighed and "bashed" for onward supply.
Police seized £226,235 from a cupboard above his oven, a kilo of cocaine, a kilo of the adulterant benzocaine, a vacuum sealing machine and cannabis.
Mr McNally said: "These are amounts of cash the crown say would be the stuff of lottery winnings to most of the general public, yet Mr Hughes had that lying around in plastic bags at his home address."
Hughes - whose BleakMoth account had his daughter's name as the password - used his dad Marshall, of Robson Street, Everton, as a "driver and a chauffeur".
Marshall also worked as a "courier", who made 10 identified trips in "slot" cars to Cardiff and London.
Pritchard was another "courier", who made three journeys to Wales.
He was arrested in Cardiff on June 1 with 5kg of cocaine - mostly 80% pure and valued at around £200,000 - hidden in the Scenic.
Judge Stuart Driver, QC, said the quantities of drugs were "very high" over the two-month period, but the plots ran for nine months overall, "so the true figures must be even higher".
He said the quantities of cocaine were "so high" that if prosecutors had said the gang played "leading roles" in that plot, as apposed to "significant roles" the Crown in fact accepted, then the sentences before credit for pleas would have started at 20 years plus.
Connolly admitted conspiring to supply cocaine and cannabis, and to convert criminal property.
He held his head in his hands as Judge Driver jailed the "bookkeeper" for 14 and a half years.
Hughes admitted conspiring to supply cocaine, heroin and cannabis, and to convert criminal property, and possessing cannabis. He was jailed for 14 and a half years.
Marshall admitted conspiring to supply cocaine.
Judge Driver jailed the "trusted and frequent courier" for 10 years.
Mulcahy admitted conspiring to supply cannabis and to convert criminal property.
He was jailed for six and a half years.
Pritchard, of Mavis Drive, Coppull, near Chorley, admitted conspiring to supply cocaine.
He was jailed for 10 years.
Speaking after the case, Detective Inspector Chris Lowe said: "These are significant sentences which reflect the extent of the conspiracy that these men were involved in.
"Our work remains ongoing on a daily basis to target the people responsible for serious and organised crime including drug supply. This gang thought they were untouchable but we have a proven track record in dealing with individuals who are responsible for the wholesale supply of illegal drugs both locally and across the country, as well as the use of violence to protect their business interests.

"We have been working closely with partner agencies and neighbouring police forces to target the people who are responsible for bringing misery to our streets.
"I can reassure the communities of Merseyside that the force will continue its fight against those involved in serious organised crime to make our communities safer and I would ask people to continue to be our eyes and ears in their local neighbourhoods and let us know who is supplying drugs so that we can take action."
