Correcting the tuning of the MiniBrute

I asked about it some time ago and got no answer and I don't think there's any info about it in the manual, so I'll leave it here for other people.

I have to do that process because my MiniBrute that I didn't use in a long  time is severely out of tune (If C3 is tuned, C4 is fine, but I get C5 at +15 cent, C2 at -15 cent and C1 at -30 cent). I haven't finish yet, I hope I won't get electrocuted (so easy to miss the tuning screw... nice job).
After tweaking it for a while, I don't have high hope I'll fix this issue. I'm guessing I shouldn't expect a perfect tuning, but to what point is it acceptable?

Eventually I was able to reduce the detuning range by targeting C# instead of C when correcting the slope and then offset by - 1 step. It still needs more work, but now I only have -/+ 5 cent of detuning across 4 or 5 octaves, which is not too bad.
