A proper flight review should include a lot more than just TAPs.
It requires math skill to master physics. That doesn't mean a physics degree should automatically count as a math degree as well.
It boils down to this: A flight review should consist of 1 hours worth of review of piloting skills. A CFI checkride is not that. Yes some review of flight maneuvers occur, but not enough to justify a BFR.
A flight review that includes just a takeoff and a TAP and maybe a chandelle is not a complete flight review. Most CFI checkrides are not wall to wall maneuvers, which is what a flight review should be.
An IPC should be wall to wall instrument refresher maneuvers, not one approach and 0.2 of tracking a VOR under the hood. This is why commercial checkrides do not count as IPCs.
If you want to argue that a failed CFI checkride should nullify your last BFR because you've just proven that you can't maneuver an airplane properly anymore, then you may have a case.
