I am working on a project that uses an adjustable progression system from 1 to approximately 250. Generally the 'toe' of the system is fairly flat but the toe and the heel need to be independently strengthened or made weaker according with the specific case.
I hacked the following together originally in Excel but feel it needs a taste of 'good J' to do it justice Series=:10+i.25 Toe=: 7.15 NB. control low end Heel=:6.5 NB. control high end Prog=: >.100%~(Series%Toe)^Heel Prog 1 1 1 1 1 2 2 3 5 6 9 12 15 20 27 35 45 57 72 90 112 139 171 208 253 Yes .. I know it is very nasty ;) but it works fairly well! Some ideas would be appreciated.
