thanks for the answer.
it's more important to have no lag than to have that count. maybe the events to create and destroy chests could somehow be used to incrementally count the buffer chests after once (after creating a new map or adding the mod to an existing map) counting those chests manually and slowly. then the number of requester chests and provider chests could also be adjusted to their real numbers (not including buffer chests).
but while those chests are counted as requester chests and provider chests, that fact should be included in the description (i didn't know about those internal workings before), eg "xxx = number or requester plus buffer chests; yyy = number of provider plus buffer chests"
ps: another small detail: in the mod settings, you write "values between 30 (0.5sec) and 300 (5sec) allowed", but the range of values in that form is "min 30, default 30, max 6000" (that would be max 100sec). if only 300 is allowed, max should be 300. what is the reason that only 300 is allowed?
i like 3600 more (resulting in a display of "per minute"), or maybe even more to get values per 10min (36000) or per hour (216000) ...
