Dude, your arsenal of RFID related products are awesome.
That meter of yours is perfect for confirming what the minds eye has been “seeing” 
when testing readers and your repeaters; but the fact it puts a number on it is a significant step better.
I feel like if we collect some sample mV figures for implants to be read, we can likely predict if a reader will work and or if a repeater will help a stubborn reader enough.
I don’t want to suggest a spreadsheet, But…
even a note/ column in the compatiability matrix.
Pretty exciting
Loving your work as usual
