Lose It or Lose It's formula to success

Maximum Weekly Reward = week# * $/lb * lb/wk + $5
Actual Weekly Reward = min(MWR, ((start - goal) - (actual - goal))*$/lb) + $5
where 
  * goal = start - week number * lb/wk
  * start = first weigh-in weight
  * actual = week's actual weigh-in weight

So, for week 5 of 2-2:
  * goal = 200 - 5 * 2 lb/wk = 190lb
  * MWR = 5 * 2 * 2 + $5 = $25

with a weigh-in of 200 (no weight lost)
AWR = min(25, ((200 - 190) - (200 - 190)) * $2/lb + $5)
    = min(25, (10 - 10) * 2 + $5)
    = min(25, 0 + $5)
    = $5

with a weigh-in of 190 (on goal)
AWR = min(25, ((200 - 190) - (190 - 190)) * $2/lb + $5)
    = min(25, (10 - 0) * 2 + $5)
    = min(25, 20 + $5)
    = $25

with a weigh-in of 188 (below goal)
AWR = min(25, ((200 - 190) - (188 - 190)) * $2/lb + $5)
    = min(25, (10 - -2) * 2 + $5)
    = min(25, 24 + $5)
    = $25
