Personally I wouldn't think wax would add enough of a layer to change a chain checker's reading. The wax layer is pretty thin.
But a chain's wear is measured in fractions of a percent, so a very small layer could significantly throw off the reading.
An 11 speed chain should be replaced at 0.5%, for example.
Yes, but a chain checker is just putting a piece of metal between links. Its not like giving a readings of thousandths of an inch or anything, it’s lines on a piece of metal and you just eyeball it. The thin layer of wax won’t really affect the reading.
