As I understand it, The LF/HF ratio is used to determine heart rate variability. As for the percentage should it not perhaps read 7.46% or 74.6%?
Well you did ask!

i know what the text says i want to know what it "MEANS"
and no it is 746.1%
ive seen it as high as 1250% and as low as 65%. The errors (spikes) seems to affect it a lot
You do raise a very good point though, if i look at the uncorrected values the LF/HF ratio is 40%
