I get it. 1200 / 40 = 30, so 40 wins at 30 points would take you to 1200 points. Wait, but that means 40 wins should give you the 15 cp reward, not the 4* from 900 points. Anyway…
Since many of us do battles at 60 points or higher, a 60+ point battle should count as 2 wins instead of just one win. Then those of is who do tougher battles can make it to top prog in 20 wins instead of everyone needing to suffer through 40 wins. Each battle takes me around 5 minutes, since it’s against 5s or boosted 4s. So 40 x 5 = 200 minutes = 3 hours, 20 minutes = ugh.
(and it is much more than 3hrs 20 mins)
