I would be inclined to take the easy option as you have so many tapes to get through especially if there are a lot of shows with just the odd track. I've been ripping the Rich Tapes on a per show basis but that's because there were at least 10 tracks per show or else full shows. But my own mixtapes I just ripped on a per tape or per month basis, though this was partly because I wasn't as organised as Rich and your taper chap and didn't note down which shows my recordings were from!
It's been a good year for the 80s shows, with content from Karl, Pate, Rich and John Leonard's Dad.
