Hi Kieren! Thanks for the info.
You might be correct in what you suggest. However so far I have not seen any complete description of stretchability. There are some words in the paragraphs about "Structure of flexible vertical spacing alists" (the link I gave in my previous note), but those are for the experts, who already know how it works. The novice does not understand, since the description contains holes, where info is lacking or implied.

Hi Kaj (et al.),if I understand it correct, the effective (resulting) distance will always be the biggest of the three, hence effective_distance = max(minimum-distance; basic-distance; padding). Is there any reason to use three, one should be sufficient.If I understand correctly, three are required for compression and expansion calculations. For example, consider ((basic-distance . 4) (minimum-distance . 2) (padding . 1) (stretchability . 10)) When compressing a page, I believe #'stretchability is applied [inversely] against basic-distance - miminum-distance which in this case is 2 staff spaces. If instead you had ((basic-distance . 2) (minimum-distance . 2) (padding . 2) (stretchability . 10)), I believe there could/would be no compression done. Others (e.g., Keith) will have a more complete and accurate understanding of the intricacies of the spacing model — hopefully someone will chime in here to expand upon or correct what I’ve said. Hope this helps, Kieren. _______________________ Kieren MacMillan, composer www: <http://www.kierenmacmillan.info> email: i...@kierenmacmillan.info
