Questions about signaling PM&R programs

Hi! I am an OMS4 applying to PM&R programs this upcoming week and wanted to reach out to see if I could get any advice on which programs to signal. The red flag of my application is low boards scores, but I have strong EC's—mentorship, leadership, longstanding interest in PM&R, and PM&R advocacy involvement, and feel like I would do a great job on interviews. I completed SubI's at two California programs, and will be doing two more (one Ca and one in Illinois). I was born and raised in SoCal, and went to school in the bay area (have never left the state). I would love to match on the west coast, but I am very open to going anywhere if it means I get to be a physiatrist. Considering these things, I'm looking for advice on which programs to use signals on.

Are there any programs with high signal to interview ratio? and similarly, any with a low ratio (ie you signal and it doesn't correlate with whether you get an interview)?

If you feel like you have any helpful insight to share, or would be willing to work with me, please feel free to reply to this thread or send me a DM!!

Also looking for anyone who would be willing to help edit personal statements/activities sections :)
