Using the following method has some problems, when there are failures in proof attempts. For example, the following sequence reports 44 primitive inference steps, after a proof failure. val meter = Count.mk_meter(); g `p /\ p /\ q /\ F`; e (METIS_TAC []); Count.report(Count.read meter); This

This is certainly true. Of course, it all depends on what you're trying to measure. If you're interested in the size of the natural deduction proof that actually establishes a particular theorem, you really need to try something like: extracting the proof using some sort of recording
