is anybody notice that explosive trap crit damage is only 150% not 200%

I found this https://wotlkdb.com/?spell=63068 ,it shows value is 100. But GM said this value of 100 does not mean that. So I randomly found a spell description, such as this Resourcefulness, it shows like below:

Effect #1 Apply Aura: Add Modifier - % (Cost)
Value: -60
Effect #2 Apply Aura: Add Modifier - Flat (Cooldown)
Value: -6000

According to this understanding, the value 100 mentioned in the Glyph of the Explosive Trap should be the value of the crit bonus.

and i find another image https://imgur.com/m23Iu5B ,it shows the same result.

All of these are based on version 3.3.
