A BFR and IPC are two totally different things. Applying the rules for one, might not be prudent for the other.
Have the instructor you're doing your checkride prep with give you an IPC signoff as long as you meet the requirements for one (which you should after your prep). He/she's going to have to give you an endorsement for the practical anyway, why not have them take another 90 seconds and give you an IPC endorsement?
Anytime you do checkride prep, have the instructor give you a BFR and IPC endorsement, even if you don't need it.
