Right but 1.4 times the sound pressure is a hard thing to relate to in the real world is what I mean. 10x the power sounds twice as loud is relatable. It is twice as loud to the ear regarcless of the SPL numbers. 10 watts to 100 watts is relatable. 3.16 times the "sound pressure" doesn't really mean much to one for someone trying to figure oit how loud one amp is to another. Sound pressure level isnt necessarily loudness as such.2 times the power = +3 dB = 1.41 times the sound pressure (what our ears hear or a microphone senses). 4 times the power = +6 dB = 2 times the sound pressure. 10 times the power = +10 dB = 3.16 the sound pressure. So on, and so forth.

From the article listed.
"Note: While increasing the power level by a factor a four doubles the sound pressure, this doesn’t mean the volume is doubled."
