Nice article indeed, thanks for sharing. I'm currently struggle to go from perfectionist with low frequency to high frequency.
I've also noticed that experienced programmers do their commits more frequently and they do the right job - they spend less time on unimportant details.
It also depends on the codebase. A programmer who works on similar codebases for 10 years is more likely to have a high impact than the one who work less and consider these codebases rather new. While their approach and skill set may be similar.
