Signal reports in FT8 are signal to noise ratio, NOT strength. Also, 
JTDX, which many of us use because it often decodes weak signals that 
WSJT-X misses, uses a different algorithm for computing that report 
(usually many dB lower). OTOH, it has been reported by good observers 
that JTDX has problems decoding signals with time instability that 
WSJT-X decodes just fine. So it's like RTTY, where multiple decoders are 
a good move.
