Antimatter replenishment rate
The antimatter replenishment rate was a measurement of the rate at which antimatter replenishes.

In 2370, Byleth, an Iyaaran visiting , asked Worf what the antimatter replenishment rate was. When Worf confessed his ignorance, Byleth then turned to Geordi La Forge and asked him if he was smarter than the Klingon. When Geordi asked him why he wanted to know, he changed the subject. This was part of the Iyaaran's plan to understand antagonism by provoking Worf to anger. ()
