**Critical Hit Chance**

I saw this amazing open source google.doc on the blue garter forums which had A LOT of Critical Hit Data, so I gathered up my own Data-Points, then asked Viridiana, who I know has been gathering hundreds of Data Points, to add his to this google.doc… 354-760 Critical Hit Rating almost. Fantastic.

After adding over 400 data-points into my Solver, I created a Chart like this to see the Linear Sloping of CRT…

Giving me a Formulae for my data points CRT*0.0233-3.3009.

Now, I wanted to create a formula which scales CRT from 354, rather than 0, like what my slope is currently doing, so using my Excel Solver (which I used to calculate the Damage Model), I got a formula of:

((CRT-354)*0.0232558)+4.9511233

Meaning, we have a base Crit Chance of 4.95% at 354 CRT.

You could also convert this into a whole number value, by changing a few numbers in the Formula to:

((CRT-354)*0.000232558)+0.49511233, giving you 0.0495.

**Critical Hit Damage**

Afterwards**,** I combined both Viridianas and a few other Data Points of Critical Hit Damage scaling.

Not as many data points, but it’s still enough for me to gauge a rough estimate of min/max values with and without crits.

The formulae I ended up with:

((CRT-354)*0.0002335)+1.4482348

I noticed something here, that both Critical Hit Chance and Critical Hit Damage use the same 0.00023X value and so, there’s a huge possibility that the scaler for both Critical Chance and Critical Damage are exactly the same.

If this is the case, as I have more data points for Critical Hit Rating, this scaler would theoretically be more accurate than if I were solving straight for Critical Damage. If I then used my Critical Hit Rating Coefficient of 0.000232558 to solve Critical Damage:

((CRT-354)*0.000232558)+1.4484746

**Final Formulae**

Critical Hit Chance:

((CRT-354)*0.0232558)+4.9511233

Critical Hit Damage:

((CRT-354)*0.000232558)+1.4484746

I’m still annoyed that I wasn’t able to hit 758 and had to leave that gap there. >_>

Hahaha, that OCD!

You might get a pm on reddit shortly by the original owner of that Crit Sheet, about an /r/FFXIVTC collaboration, btw mate.

Well, nothing yet from them. You didn’t, like, tell them my reddit name was Viridiana or something, did you? :p

Nah, I know what your reddit name is hahaha. I’ll PM you there

In previous post, you said real game constants are probably whole numbers. Did you find accuracy results only using whole numbers for critical hit formula ?

Yes! All formulae in this game use whole numbers and on the 1st I’m going to go in depth about some very special information.

Unfortunately I’m on holiday, so I weren’t able to do any blog updates.

there seems to be additional 1% crit given at 781

Apparently there is a jump in crit% at 781, a free additional crit% increase

Is there a Source for this?

Just filled in more points on the ole Crit Sheet. No jumps at all up to 840.
