Every 16 chain revolutions the same tooth on the SMALL sprocket contacts the same chain link = 0% optimal wear rate
Every 16 chain revolutions the same tooth on the LARGE sprocket contacts the same chain link = 0% optimal wear rate
The lower the chain revolutions, the more frequently each chain link engages the same sprocket tooth, so greater and more uneven the wear.

Chain link adjustment When changing sprockets, you can adjust Chain Links to maintain (nearest to) current Sprocket Centers (eg: to keep motorcycle rear wheel within adjustment range). Check Lock Centers and adjust sprockets - Chain links will adjust to maintain nearest to current Sprocket Centers.

DON'T BREATH THE DUST If you're cutting blocks, concrete, stone or ANYTHING and there's DUST - DON'T TAKE THE RISK
Don't cut it, or cut it wet so there's NO DUST - Silicosis Sucks
And if you're cutting wet, wear a mask - theres dust in the spray mist too!

How should we spell it?
