To be fair, from what my sensei said I think the RM here only just started picking up on little things like that in the sensei classes and really coming down on them (cant remember when exactly, but we got a new RM near the end of last year) so she probably hadnt really thought about it before, especially where it concerns the lower grades (sensei who picked it up is a B&W who either is, or is getting close to, a brown belt).

the GKR preference is still for the foot to be turned in
Front foot in long forward is supposed to be with the outside straight ahead, and the back foot turned to the front to a degree that I keep getting different answers for

but is not supposed to be straight on to either the front or side wall. Or at least that's what I've been taught

.
Kay things that seem to be working: keeping my knees bent as I step through, using hips more (and boy is that proving to be difficult), and what monday sensei suggested (different to the one who pointed it out) slightly turning my front foot out just before I step through and keeping my back straight (another thing that's proving difficult).
I seem to be okay with the step through and punches, but I still keep doing it a
lot on the turns and the blocks. Have noticed that I do tend to lean (in various directions

) when I turn which isnt helping.
