You misunderstand my point - I know that you need to invest more and more points to get to the consecutive breakpoints, but I wouldn't exactly call the returns "diminishing", when every other frame is so much more valuable than the previous one (i.e. an increase from 12 fpa to 11 fpa is a ~9% increase in overall speed, while 4 to 3 would be as high as 33%).
In fact the returns are increasing, just that the system works with breakpoints rather than raw values.
Also, according to speedcalc, it's not always the case - for example an amazon needs 4 block speed for the first frame drop(17->16), but only 6 (so 2 more) for another one(16-15) when she's wielding a scepter.
