I realise that is not necessarily how its being done, but are you
also saying its impossible to achieve a log flow rate from an injector
designed that way for a linear change in fuel pressure ?

Sorry to be pedantic, I never said an increase in pressure results in
a drop in flow-rate, so I dont have it backwards - I had it forwards
but not at the proportionality rate you report...

I am not a pedant as I do not fit the precise description of one.
