Good to know, just grab n go! No complex mathematics behind the decision.The rear mech? No clue, it was just what I had in the parts box that looked to have a decent cage length. I didnt buy it deliberately for the job. I suppose it'll be the long cage version that the web describes as 85mm.
Looks like some relevant discussion here, particularly a chap down the page, linking to a video, saying he ran 45 on a bike from 2012. Ok not that old but somewhat. https://www.mtbr.com/threads/deore-m4100-10-speed-11-46-compatability.1174701/
