Thank you for the info.

However, I am looking for more complete and accurate data. The graphs and formula in Danotes are for "mid range" profile shift. It is not clear what "mid range" means, and what will be the formulation for an all recess gear where the shift factor is 1, or for negative profile shift?

Detail information about algorithm you can find in AGMA standard 908-B89 (page 541-552). Unfortunately I don’t know some detail web resource for it.

Software from Web Gear Services calculates AGMA J factors - it may be worth looking into
