Genuine question!!

Will the cut of money argyle make from the play offs, be enough to clear any remaining debt ?

Probably not, its estimated it'll be around £150k - £200k from the three play off games.

Argyle receive an eighth of the gate money from all 4 League 2 semi final games (50% goes in a pot for other League 2 sides), and receive 25% of the Wembley gate money (as do Wimbledon/ Accrington) and again the 50% goes in a pot for the other League 2 sides.

And then 50% of that total goes to paying down the PAFC debt which doesn't benefit the playing side of the club, but certainly enhances the value of Jimmy's and Si's investment. In effect, it goes in their pocket, given the way the budget is planned. Nice work if you can get it.
As Jimmy says, football is all about being careful and austere, and then getting lucky. He probably gets more bang for his buck at PL2 than he gets from growing food in his "world wide agriculture".
