22,5kper season from games
29k is total boost so far every one gives 2k
11,5k from stars on jurneyman
15,5k from stars on professional
if we make X the number of boosts
22,5 times 2 + 11,5 + 15,5 + (29k - 2 times X) = 72k + (29k - 2 times X)
hope it helps, also on a site note the elusive 500 pts that was missing in bort's FAQ is from last jurneyman level it gives 6500 and not 6000

for people with earlier toons the 20% stars added on all 3 levels is 13,5k for each
so in general you could use the number 36k as the number of SP earned a seasoned from non boost
also after doing all this math i realise that a total player build will have 210K pts and not 209K since you start with 1k get 180k earned and get 29k from boosts......
