Hi,

if you want to use F1 and F2 values for you comparison of your generic formulation with a reference formulation, you may only have 1 point after 85%, so you need 3 - 4 points before 85% release.
Also you need to test 12 samples.
If your component is rapid dissolving (> 85% in <=15min), you don't have to perform F1 and F2 comparison.
Besides this: F2 should be between 50 - 100, so based on your calculations: equivalence isn't shown.

For a reference about dissolution comparison: http://www.dissolutiontech.com/DTresour/899Art/DissProfile.html

Kind regards
