Crossover tuning

I suspect the Crossover tuning chart is just someone's interpretation of Steve's description, which as I read it conflicts with itself to start out with. For a decent sounding modern compromise "chart", try using one for 19-limit just, and modify that by only flattening the thirds about half of what's indicated. And remember, charts are merely starting points that don't account for the challenges inherent with the instrument. A correctly tuned chord or octave usually doesn't line up exactly with numbers on a chart when checked as a single note. 

I've noticed that, too.  The draw reed plate description does not match the chart on that site (the blow reed plate seems correct).  When the description says 4 and 8 draw should be "once cent higher than 2 draw", the chart says +1 instead of +5.

Here's the way I interpret the description of the draw reed tuning (given that he has ranges in the description and not exact amounts):

Holes 1    2    3    4    5    6    7    8    9   10

Blow   0   -5  +1    0   -5  +1    0   -5  +1    0

Draw +8  +4    0  +5  +2  +6    0  +5  +2  +6
