Light strike hits 1x
Heavy strike hits 1x
1x equals both fists hitting, 1 fist means you missed or were evaded
The 3-4 hits you see are because pugilist weapons do 2 attacks, so on 3 punches, that means one attack landed, the other was evaded or missed.

So, you're just a little confused as to what is happening.
No worries, it happens to us all from time to time.
