How to get PROPER swing in Renoise, with, for example piz midiswing?

According to some pictures on this the link provided earlier in this thread: Global Groove - Documentation / How does it work? - #6 by fladd - renoise never hits exactly 58% of a drum machine swing, but a floating point percentage near it? Might this be the reason I don’t like the swing in renoise fully? And if it never hits that exactly, it most likely never hits most anything in exact percentages either?
