Here is a combat power level calculator i'm working on exclusive for mabiguru.
This is just for CP, no bells and whistles added on. There will be other tools coming soon for other purposes, such as finding out what monsters would work to train your skills based on your CP, and some other types of calculators.
To test the accuracy of this calculator requires you to have the client mod that shows CP, not sure if mod discussion is allowed here so i won't be giving info on how to do that. If you secretly have the mod and don't want people knowing you do (by publicly posting results) feel free to PM me your results instead.
Here is the test calculator:
CP Calculator
With private testing it was found to be 98 - 99% accurate. So now a larger sample is needed. Please post your real CP indicated in-game using the mod, and the CP the calculator gives you. If it's off by more than 5 points, it would help if you also posted reasons why you think it's off by so much.
The CP data is taken from this topic:
Kotei's CP Charts
If there are any corrections to be made to this data, let me know.
Thanks.
P.S: Don't bother pointing out that there already are CP calculators and other similar tools out there, the point of this is for guru to have all these tools in one place.
