About 10,000 heating and coolings; this stress is likely the life-limiting factor when deposit issue is avoided.
Does the dry burn add to this thermal stress? Perhaps, but only slightly as the number of heating/coolings is likely worse than the max temp. And as consistent performance can be achieved over a substantial period, that doesn't really matter
