My understanding is that one should lean using the "hotest" cylinder as

of "hotest."

As others have stated in other words, the proper procedure is not to
lean to the "hottest" cylinder, but to lean to the "leanest" cylinder.

IOW, look for the first one to peak, and lean to that one. The fact
that the leanest cylinder may not be the one with the highest EGT is not
a consideration for leaning.

Note also that the leanest cylinder will vary over time. It won't
always be the same cylinder on every flight.
