No 50 %

When you reach level 41 it is said you get +50% purple points.  But when i got to 41, in megalopolis,   then points went from 1320 to 1650, from 2210 to2763, from 11260 to 14075, from 6000 to 7500,  to give  some exemples   And that is not 50 % but only 25 %. So please explain Lanna or who ever at EA.   Is that the same with other players ?     Anywhy it is strange to give more points now ,and not souner , that you are in the last week where you always get double points.
