How the Bonus Rating is worked out using two factors:
1. (Bonus - (WRx5%))/Deposit = Expected return on your bonus after completing WR, based on 5% house edge slots.
This returns a figure from +1 to -4 (e.g. -2 would mean you would lose twice your deposit by the time you complete WR)
(Note that for phantom bonuses the bonus is deducted off the expected return figure).
2. WR/B/% = Value of the bonus as a factor of how big the WR is & how big the bonus % is.
Figure = 0 to 200. Lower is better.  (e.g. A 200% bonus with a WR of Bx30 would give a figure of 15.)
To make this compatible with the (1) it is divided by 100 for the final calculation:-
Because (1) is often negative, we 4 add to make all the ratings positive, then deduct the value defined in (2)
Examples:-
Ladbrokes 1. (Bonus 100 - ((WR 800x5%)=40) = 60 of your bonus left after WR.
Return = 60 / deposit 100 = 0.60
2. (WR 800/bonus 100) = 8  Divide that by Bonus 100% = 8.
Divide by 100 to make compatible with (1); 8/100 = 0.08
Rating = 4 + 0.6 - 0.08 = 4.52
