Elite Excel appears to be using the normal Charge Weapon damage scaling when calculating damage. To replicate, acquire 3 stacks of Charge Weapon (Elite) and hit a target. Then, limit the potential and acquire 3 stacks of Charge Weapon (Normal). Note that the damage done is exactly the same, despite the Elite charge only being reduced by 1.

Example:

Weapon: Excel Saber
Classes: Ghost/Kensei (No Claret Calls present, no debuffs applied)

With 3x Elite Charges:

Critical Hit! Cadaverous Collector attacks Prinny with Totsuzenshi and hits them!
Prinny takes 481 Slash physical damage. (Totsuzenshi)
Cadaverous Collector recovered 1 FP.
The battle has ended.

With 3x Normal Charges:

Critical Hit! Cadaverous Collector attacks Prinny with Totsuzenshi and hits them!
Prinny takes 481 Slash physical damage. (Totsuzenshi)
Cadaverous Collector recovered 1 FP.
The battle has ended.
