Miguel, thanks for the suggestion.  I had something similar in some notes I’d kept, but with 40 degrees as a target instead of 35 (2” to right of the v notch instead of the TDC mark.)  Looks like what I had was also Tencent but from earlier and the procedure has been revised back a bit.  I’ll try it that way tomorrow.  Thanks again.

Fourth post down quotes Tencent’s procedure. I use it for every 2.1 I time.
I’m also at 7K elevation. 
Good luck
