53t to 52t equals one Half a thread pitch shorter.
rear 3t increase equals 1.5 thread pitches longer.
basic bike-ology, 101
there are no half links (actually ONE full pitch length) for multi-speed bike chains, that I've seen.
and you count links wrong, or your bike is insanely tiny.
can i assume that you meant 106 links, and 110 links?... and you might want to go re-count now.
off bike, i count just the outer plates, then add one to account for the Quick link/Master link... then multiply by two.
