Using your calculator, his actual PBs for 1500m and 10km give 1:45.9.
His estimated shape of 3:28.5 with 26:30, 26:35 or 26:40 all give times in the region of 1:45 high.
Using his 3:28.9 along with the half marathon he ran that year 59:22 gives 1:46.0.
So based on your own calculator you should conclude Mo Farah would run slower than 1:45.5 at least, and be more comfortable saying 1:45/1:46 rather than 1:44.
Did you not read my post almost immediately above yours? I feel like I just explained why I didn't arrive at the same conclusion as you.
