  I'm not making much progress with Camelot w.r.t. to them explaining why the pre-draw jackpot pool estimate has now been used as a post-draw exact jackpot pool (like a Super Draw in effect) for the past 4 draws. I was tiring of manually typing in the "correct" calculations table on each individual lottery draw page, so I decided to write a program to generate it.

  Basically, the program will either use an estimated ticket sales figure I type in manually or start from 16m (Wed) or 30m (Sat). It then adds a 500,000 pounds adjustment to ticket sales and sees if the 5+bonus prize formula (or the less accurate 5-match formula if there were no 5+bonus winners) works out. I can't use the jackpot individual prize figure, remember, because Camelot are using the pre-draw estimate for the jackpot prize pool.

  If the individual prize would be too high, the adjustment is divided by two, subtracted from the ticket sales and then the formula checked again. If the individual prize would be too low, the adjustment is divided by two, added to the ticket sales and another re-calculation of the formula occurs.

  If the individual prize is exact, then the ticket sales are used to calculate all other variable tiers, with a warning if any don't match what Camelot issue. The result is a reliable set of figures that didn't exactly match the ticket sales or jackpot prizes I'd previously put up for draws #1608 to #1611 (because I'd done the adjustments manually, not by a program).
