The point being that if you adjust forward power for full scale meter
reading then 3:1 reverse power will be at half scale, 2:1 quarter scale

"then 3:1 reverse power will be at half scale" is gobbledegook.

Would you like another guess?

If diode voltage drop is insignificant, quarter scale (rho=0.25) equates to
VSWR=1.67.
