Thanks Brian, and as I said earlier, this was for the bin, just wanted to see what the new tool could do and wasn't going to post, but after Andreas, I just thought I would bolster things, so no sweat.
Since taking this shot I have changed my approach & settings
(albeit for some reason Andreas thinks not) but the R5 & R3 are set up totally differently, partly down to their guts, but also in how I use the options now with greater efficiency, especially for BIF. In addition, I stopped thinking how I shot in DSLR and mirroring it to Mirrorless, how wrong was that. I would wager many Canon folk shoot Case 2 -2/+2/0 all the time, in doing so the camera doesn't deliver, so using Cases for the type of shooting you are doing is paramount. Mirrorless is also far more sensitive to heat haze compared to DSLR, so for those who still have one, it's a bonus.
Anyway, I will try next time to post a more engaging one with more elements to salivate over.
