I'm using the 7.16.3 stack, I remember earlier the throughput dashboard was showing rpm metrics, why did it become tpm?

Is there any difference between request/min (rpm) and transactions/min (tpm)? Would it be friendlier to use tpm?

Is the calculation method of tpm and rpm the same?

As shown in the picture, I select the last 3 hours, and then the tpm is 182, then the calculation formula is 3 \* 60 \* 182 = 32760 requests?
