sfz Technical(ish) Questions

Hi, I've just started to dip my toes into sfz programming (by converting some of Dimension Pro's excellent drum sfz definitions for use in Session Drummer 2) and I've got a couple of questions.
1) Is there a formula to determine velocity mapping across a given number of samples for a given instrument? For example, a snare drum uses two samples, sample 1 is triggered between velocity 0 and 80, and sample 2 is triggered between 81 and 127. I've noticed that all multisampled drums are shared unevenly like this, so I assume it's deliberate, but is this sharing judged by ear or is there more science to it?
2) I've figured out that the 'group' opcode can be used to set up choke groups (eg open/closed hihats) but what does it mean when the region isn't switched off by the 'offby' opcode?
Hope somebody here can help,
Thanks :)

    Just judge it by ear.

    You might want to ask this on the Instruments Forum. The SFZ developer is pretty active over there.
