  Yes, this is a good idea, thanks.

  I implemented it and am trying it out now, with a small modification
though: the above would produce much smaller values for the delta, so at
first I'll try with only two samples at both ends of the range.

  Btw, after yesterday's changes the charger seems to work much better.
