Add a kill time evaluation to all star points

I would like to find meaning in reducing kill time

For example…

· Focusing support on one DPS, battle ended in 10 minutes.
· Everyone was strong, battle ended in 7 minutes.

In the above case, even though the same numerical values ​​were given, I think that the latter is superior.

normal pts: MAX (your percentile, (your dps / # 1 dps) * 100)
dps pts: 10 = (your dps / # 1 dps) * 20
time pts: MAX (10 - (your kill time / # 1 kill time) * 100, 0)

If it is shaped like the above, can you do valid evaluation?

My english is very poor , sorry.
Thank you for reading.
