[Paul Gacek]

Thanks all for the feedback.

T1 correction is now made and now off to make a cup of tea (there’s a Brit in me somewhere....).

I can't answer your question ["does it make a difference?"] because I don't have a K1, but I did build a K2, and based on that, I think the answer is "Yes, it will make a difference."
