Secondly, metastability is a probability-thing, i.e it occurs always! At high frequency, comparator has less time to resolve input and so you see a lot of metastable events. However, it is very difficult to see metastability issue at low frequency because probability is much-much lower.
Agreed - and add to that - higher frequency = less gain.
one perspective is time domain and the other is frequency. Both are valid.
