Not sure I've understood the series TBH, but is the npeel == vf / 2 there specifically for the "unknown number of peels" case? How do we distinguish that from the case in which the number of peels is known to be vf / 2 at compile time? Or have I missed the point completely? (probably yes, sorry!) Thanks, Richard
