In the case of these Hulda frequencies and for THIS item there was a typo in a print of her book that propagated through the internet. The CAFL numbers keep growing since users find new ones and of course the critters evolve…
The second typo I found was in Echinococcinum, I fixed that and ran it yesterday with what appears to be good effect.
But remember since two channels are being run the front one with the CAFL frequencies will always be close, plus the F125 allows fuzz which spreads the frequencies up and down by 1.
That said; the real Rife frequencies and how to generate them are held tight by our owners...
