Critical Ratings are Only at Two Thirds Value? - No! Solved!

I am trying to get my head around the Critical Chance calculations. Trying to manually reproduce what we see on the screen when we press "C" or "I" and look at the "Spell Critical" or "Weapon Critical" number.

Time and again the numbers I take from the CP Warfare or the numbers I see on my sets or the numbers I see on my "K" Skills screen do NOT add up.

It appears that my "Critical Chance" numbers on my sets are being applied approximately at TWO THIRDS value. Charitably allowing for rounding issues I can arrive at the number which appears on the "C" or "I" screen but only after I take 2/3 of the stated value.

Is there something I don't understand here?

I accept that compared to most of the people who post in these forums that I am a scrub. I have a lot to learn.

I am assuming that 15,000 at level 50 is the number I should be using as representing "15,000 critical rating points are equivalent to a Critical Chance of 100%".

Additionally, I noticed that "Spell Critical" and "Weapon Critical" start at a base of about 10% on the screen. So any amounts we try to add to our crit chance will be added on top of that 10%. Am I correct?

Yes, I do know that our base crit chance is 10%. But our crit damage starts at 50% but on screen starts at zero. That is, the representation of data is not consistent. But that's a side issue.

For the record I am not getting confused with, nor wanting to discuss "Critical Damage" which we can see from the "Advanced" option of the "C" screen. I am not at all questioning the figures we see there nor am I buying into any 125% debates.

I am hoping someone has noticed this "two thirds" problem or I am hoping someone can show me how wrong my calculations have been! Thank you.

    Replying to myself but for sake of an example:

    Naked character. Precision from Warfare CP screen. For me it is "320 Critical Chance". Not sure what you see.

    320 x 2/3 / 15,000 * 100 = 1.42222... 10 + 1.4 = 11.4.

    11.4% is exactly what I see on my screen.

    You are not missing something :) 2191critical (What you get from a top level weapon or spell power potion for example) is 10% critical. So you have to calculate from there for your percentage. Hope that helps and welcome back.

    That buff got changed to 2629 (12%), but your 1% value is right.

    1% crit = 219 critical rating.

    You can also test this with Light Armour as each piece gives 219 crit, which puts your rating up 1%.

    Would like to know why OP assumed 100% is 15000.

    Well... as an amateur at this... I (cough) read it on the internet lol...

    http:/https://en.uesp.net/wiki/Online:Spell_Critical_(effect)/

    MCV = 2 * Level * (100 + Level))

    So at 50, the Maximum Critical Value is = 2 * 50 * ( 100 + 50) = 15000

    The page was last updated October this year so I assumed it was pretty good.

    21910 is indeed the correct MCV.

    Thank you for that. I've tested it against a range of my sets and I could take advantage of the free CP resets too with Patch 32...

    Basically you just simply add the "Critical Chance" (however it is labelled) from all the sources and then divide by 21910. Truncate after three significant digits. That gives the critical chance. As a percentage as presented on the screen simply x 100. Which leaves precision down to one decimal place, as we see on the "C" and "I" screens.

    Thank you.

    (15,000 / 21910 gives 0.685. Note exactly 0.666 but that's obviously the source of my 2/3 thing. Even allowing for dodgy rounding I just couldn't get the numbers to fit!)

    I'm unable to edit my original post to include a warning so I took the liberty to edit the label/heading.

    I don't want people to get the wrong idea ZOS are ripping us off our precious crits lol!

    Actually that formula is technically correct. Your "mistake" was to assume that you are level 50. In reality you are level 66.
    2 * 66 * (100 + 66) = 21912
    This is an old relict from the time before champion points were added to the game. Back then, when you reached level 50 you became a veteran and then you leveled from veteran rank 1 to veteran rank 16.

    The more you know!
    I came across the max value by chance on a build editor when adding acuity and it gives you +21910 crit rating for +100% crit chance.

    And some other testing confirmed.
