I don't like the idea of fitting a single curvy line that runs exactly through all the points on your graph. A regression curve that allows for some uncertainty of measurement in each groups size would be more convincing. You can get some idea of that from the way your 3 group average varies by up to 0.2" from the single measurement on the left. Looks like around CBTO 1.915 should be your sweet spot. Nevertheless, very good work and I wish I had data like that.

223 Rem for 60 gr Vmax

The graph was plotted using Excel - using exact figures. I hear you though not keen on use of a regression curve - we OCD over collection of such results, change seating depths at three thousandths of an inch at a time - there's no way I'm going to use a regression curve to draw a 'best fit' - its either doing something or not - thats my view that may differ from others.
However I'm more OCD on these sort of things! Can be a hinderance in some aspects !

Thanks though.... you too can attain data like this...
