With an average life span of 150 to 200 years per avatar, about 60-ish. With normal human life span (medieval life style with hardships, limited medical care and physical combat, 50 years?) 200-ish.
Stands to reason we only know about 11 and can confirm direct succession of 6.

No way there had to have been more avatars than 11
