how often are you all-in per 100 hands?

Over 8k hands (small sample yeah yeah) my win rate seems to stagger - I will be level or slightly positive winnings until I get all-in, then stay level again until the next all-in. Sessions where my nuts dont line up with the villain's second nuts tend to be break even or slightly down. It seems all of my profit comes from stacking someone.

Obviously this makes a degree of sense but is this normal? Just curious. I play on Absolute 50NL if it matters.
