Thanks Sunka for the link. I remember watching it a few times a year or so ago. Always good to refresh.
The one thing I'm struggling with is planning the merge and lead turn. I seem to find myself a lot where I don't have enough horizontal separation to avoid the HO. When I initiate the lead it has me in guns, often enough where I'm getting hit badly or worse. If they miss I've got 'em, but a good HO shoot'r has me.
I remember being told to plan the merge as soon as you see the dot. I should probably add (if it's relevant) a lot of these happen in base defense situations, where the bogey has considerable advantage in both E states. So while I'm trying to get level, get some speed, and set up to turn to his tail, he's bearing down guns blazing. I could HO too, but I'd rather not.
Visualization is my best method to learn. I can be told 1k times and sometimes it just doesn't make sense 'til I can see it. So the more videos the merrier.

Thanks.
