Detected rate does not need to be exactly right (which is impossible without long test), it only needs to be close enough (I'd say +-1% or so is still fine without causing problems)

This value is used to set sound and other internal timing values, vsync is still 100% locked to real hardware sync.

Should this divide by 2 give the real line frequency ?
No, it always reports frame rate, not field rate (x/1 if progressive, x/2 if interlaced)

/1 in the log means rate is used 1:1. /2 would be used if PC rate is 100Hz/120Hz. (=it is shown twice / Amiga field)
