Good question, I raised a similar point about non Justin material Making sense of basic Chord Sheets
Justin with his song lessons and app gives what you need. The problem I found was that a lot of other sources is that they only show when the chord changes, not the bars between. Strumming patterns seem to be only occasionally given. I suppose it is a bit like Justin’s song lessons where he gives different patterns depending on your ability. In terms of tempo there are sites that give this for most songs.
I am currently having a try with Ultimate Guitar for the songs that Justin has not done (yet)
It will be interesting to see what others have to say.
