Hello S.z. Liang,

I just got reply from PowerQuad expert of SE team as below:

"

"res" is usually short for "result", which is the result computed by the formula.

"ref" is usually short for "reference", which is the actually result sampled in real condition.

This accuracy computing formula is just to convert the percentage error to dB way. This is no special method here.

"

Have a great day,
TIC
