suggested mill gap

I've been using 1.2mm to mill my grain with great success, my last (cold sparged) brew had 86% efficiency, but I found this -

Speidel are advocating 1.6mm! Has anyone here gone that high?

I started milling with a bigger gap than before because of Speidel's gap recommentation. At approx. 1.4-1.5mm depending of kernel sizes, as I felt that 1.6mm was just too big.
Compared to the time I milled at approx. at 1.1-1.2mm, I consistency lost about 5-8% of mash efficiently (I sparge) on every brew, from high 70s to low 70s (some times even just high 60s).
I went back to my old lower milling gap practices.

PS: Somehow, on my last brew, my mill shifted from 1.2mm to 0.9mm. I ended up with my normal high 70s efficency but faced my first ever wort fountain and a giant one! So from experience, 0.9mm is bad :D

Ok - I'll forget I ever read it and stick to 1.2mm. I've yet to have a wort fountain, and I've never yet forgotten to add the bottom filter - so I still have some classic BM experiences to come...
