PSLF/EDRP strategy: Does this actually work how I think it does?

Future grad planning to work at a VA as a Psychologist. My strategy: enroll in IDR, make minimum payments (~$600-900/mo on a ~$100k salary), let those count toward PSLF's 120 payments, then get reimbursed annually through EDRP for whatever I paid. Effectively $0 out of pocket for 5 years worth of minimum payments while the PSLF clock runs.

After EDRP's 5-year window ends, I'd pay IDR out of pocket for the remaining 4 years, then get the rest forgiven under PSLF (I already have about a years worth of PSLF payments from before grad school when I worked for a non-profit as well).

Am I understanding this right, any major holes in this plan? Anyone here actually done this combo? Would love to hear how it played out.

NOTE: For those wondering why I don't just take advantage of 200k from EDRP, my loans are pretty substantial… like somewhere between 350-420k. Yes I know that was a bad idea but it's in the past, I'm talking moving forward.
