Ok here my results.

By homebrewing HQMS out of HQ it looks like essentially less HQMS is formed than is used normally in standard E6 first developer.
This means of course in addition that there are residuals of more active pure HQ. Same Times, routines and ingredients as in my actual homebrew gave me Slides overdeveloped about one Aperture, with weak D max and an overall yellow/green shift.

Not too promising… But this have to be said too, tonality looks good, color crossover is not visible or overlaid by color shift at the moment .

I’ll try the next days a second formulation where Solution 1 has significant more time for reacting (24 hours instead of one), but I suspect pure HQMS is definite the better option and this processing variant is not worth the hassle…
