True but 2.5 mm is so very far from 0.1 mm that you’d need to unwind the screws like 9 full turns. If the threads are even long enough for that the hotplate will be very tilted between first and second point, increasing the risk of misalignment or worse problems.
Also many people don’t have feeler gauges, which is assumingly why it’s suggested to print the 2.0 mm one.
