My apologies QDMQDM, I didn't realise you drive a Cub. I am somewhat sensitive to this issue after learning the hard way about what happens when you land a Cessna even a few knots too fast - $1500 insurance excess on a new firewall.
I am now a strong believer in "the book" and practicing with rearward CG and at gross weight as well. One thing I wish for is that performance charts were of a standardised layout - Cessna's seem about the most comprehensive, I also wish that the use of "factored" (ie +15%) and "non factored" charts was discontinued because its confusing. The most incomprehensible charts I've seen are the good old Tobago's.
