Sheldon's chart refers to Sugino/SR bottom bracket spindles, so your YST spindle may not match. Go with your measurement.
OTOH, if you have room to allow the right crank to move in 3 or 4mm, you could go with the shorter spindle. If I were working on it, I'd try it out and hope I could exchange the BB if it didn't fit. You make the call.
