from 3 out of 9 to 4 out of 10 to 9 out of 15 five more in a row

x = saves y = attempts

.33333y = x and .4(y+1) = x+1 which is x = .4y-.6 sub this into the forst equation

.33333y = .4y-.6

results in y = 9 so x = 6 add 1 attempt and 1 save to get 4 out of 10

then add 5 more to get 9 out of 15 = 60 %
