I’ve been testing various ways of correcting the M2P lens distortion and currently I’m using the lens distortion in Resolve 17.2.1 Studio at 131. Just wondering what settings others feel are optimal? Example attached, top is untouched bottom is 131 correct lens distortion.

The lens correction is only when recording in H.265, and I know that (some) others have previously said the benefits of H.265 v correcting the distortion (it’s not available in the free version of DR) are just not worth the bothering … and stick with H.264. Personal choice, obvoiusly.
Also, to obtain the best setting if you are going to correct, it’s worth drawing up some squared paper, with bold lines, and filming this carefully/squarely/centrally positioned, and using this as the basis of selecting the optimum setting in DR … or in any other editor with barrel distortion correction.

My lens correction setting for my M2P is usually between 0.15 and 0.2.

Actually I should have put 0.131 apologies for that. I use my drone for footage for the various filming projects we do so it needs to be 10bit to get the most out of it in matching to high end cameras, so H265 has to be default really. For me matching is to match the look of the other footage which is mostly 17mm or 35mm and as such the M2P footage has to look the same width perhaps more than trying to line it up to markers. Generally I go for the sky line but often as above that isn’t straight. We often film our actors on bridges and they are a particular issue at times. The 0.131 setting seems to be the best average, In the older versions of Resolve the lens correction was a different tool where I’d use 0.265 for red green and blue but with the newer one it doesn’t seem right.

Now there are both the “Lens Distortion” in Open FX on the Colour page …
… and that still has it by channel.
They (sensibly) added the new “Lens Correction” in the clip inspector (Cut and Edit pages) …
… and, indeed, different values are needed to achieve the same.
I only moved to Studio post v17, so don’t precisely recall the options available in v16, and was one of the several reasons for buying Studio (for my GoPro footage - don’t personally have the M2P).

Ah missed they had done that, either way it works and doesn’t add another OFX to my timeline which is always good. I use an ACES colour space so DJI and GO PRO 9 both have their own DCTL luts to get them in the right colour space to start with which is another problem with such footage. Thanks appreciated…
