Just double checked and it's maybe slightly less, although I'm sure I've seen 14 but that was probably a bad one. My last range session was a week ago and for my 8 Iron it was an average of 8 degrees out-to-in, worst was 11.8 degrees. Although also all this data comes from a Garmin R10 so may not be the most accurate, but it's what I've got.
And yes, my face used to be wide open, looking back at my first session with the R10 it varied a bunch but the most with my irons was 9.8 degrees right/open relative to the path. In that recent range session from above it again varies but the bulk are between 2 degrees open to 2 degrees closed (to path). That's been the biggest change for distance, kinda obviously, just getting a much more efficient strike.
Had a couple that got out to 225y and all the others were 200y+. Six of eight fairways found and all close to target line. Shame my irons were pish, bar one very nice 7i which I hit to just inside 3ft for birdy on the par 3 third, but you can't have everything 
Course still green and lush so not like I was getting crazy roll out. That sub 90 on the harder course is within reach if I can keep this up.
Ended up with an 82 & 83 (par 70)
