If the seat tube angles are different, this won't be correct, so it's best to measure up from the BB vertically. If you put a spirit level along your saddle, you can measure setback (#2 in your list) using a plumb line and measure vertically from BB to where it intersects with the level.

It should work PERFECTLY if you get all the measurements right.
