not sure what numbers you want but yes i can BTW I am still waiting to see your credentials to be a expert. Here is a photo I took when I got home today 42.5 Deg 6-pipe loop top layer at 3. I expected in the mid 30's I never said a 6-pipe was best. Its not my way. We do all kinds of loops. We do a lot of horizontal bores these days too. I do not claim the 6-pipe. It has been a main stay of the industrie for over 20 years.
