Lessen exp needed for rank ups

One day i decided to look at the exp i would need to get highest rank in the game(marshal)
oddly it didn't show but the rank under it general 6 needs 26564451 exp
after doing some math i realized it would take like 50 yrs to reach general 6 WDF and i have abt a 2 kdr! so who is gonna play that long!
Ive gotten 361638 exp in 8 months of playing i play a pretty long time usually daily at least like 2 hrs

26564451=general 6
361638=8 months of playing
26564451÷361638=73.4
73.4×8=587.2 months of playing
587.2/12=48.9 years of playing

if u cant understand the math there ill explain if 361638 exp is 8 months of playing daily
then 26564451 is 587.2 months of playing daily
which is 48.9 yrs of playing!
