One more Autocord question

I have shot a few rolls with my new to me Minolta Autocord -- amazing camera. I have noticed that the frame spacing is slightly irregular, varying from 3/16 to 5/16th between frames. Nothing bad is happening - no overlaps or anything like that, and I am getting 12 good frames per roll. I am assuming this is normal -- is it or does something need adjusting?

That happens on my Rolleiflex too–it's not a problem. The only MF camera I use that has completely even film spacing is my Super Ikonta A, which uses a red window.

If no overlapping, then everything is good.

Thanks. Maybe without sprocket holes the film advance is a little less precise in 120?

My Rolleiflex is the same way, some small variation.
If you notice it getting worse it may be a sign that it's due for a CLA.
