Online Skillup Calculator

[Pag0]

Thank you for putting the time in to create these forms. Will be very nice as an extra tool.

Talking of caps...
A Tradeskill with an easy difficulty, no alternate stat, tried at a skill above 190 with a prime stat of 355...
..gives a chance of 8.5% for a skillup on a success.

Alas, I think the second check caps all successes at 5% if you are above skill 190.

Maybe a check for N>1000 is missing here?

As many others, I made a crude excel sheet for my own purposes, but would love to have a nice calculator here at EQTC.

Cheers,

Version 1.1 up

Thank you all for your comments!!

I made some tweeks and changes ... let me know what you think!

Added in the following:
- Skill level now has a hard upper limit of 252
- Reformatted the form to make it clearer (I hope)
- Reformatted the results form to show # combines per skillup
- Success rates are capped at 5% on the lower end and 95% on the upper end
- Changed the forumla so you cannot exceed 100% chance at the first roll
- Added in error checking for trivial <= skill, and skill >= 250

Let me know what else needs to be changed!

Very nice calculator !!! Any plans to allow it to calculate for +10% and +15% modifier items such as the Akhevan Shears in the future?

I had thought about it After I get the formulas correct I'll probably add in options for the different stat bonuses.

It treads dangerously close to "me too" but thanks to both Ariaya and Ngreth for their work on these calculators. My guild's webpage now has links to both of these works and I want to say thanks for your time making these happen.

I like the idea that below 190 skill you might consider Not Using a geerlock when skillpoint farming in mass combines.

Ngreth,

I think you still have a bug somewhere in your cool app b/c it is still giving >5% chances of skill ups (on success) for >190 situations. My udnerstanding of the formula is that you can't get better than a 5% chance after 190.

Ariaya,

Either I am doing something wrong, or your calculator has a minor bug.

I threw in some random numbers - just to see what the results would be. I used:

Tradeskill Level 150
Prim stat 210
Secondary Stat 180
Recipe trivial values from 160-220
No change with geerlock

Now, why does it always come back and say "ditch the geerlock"? It also shows the combines per skillup as more with the geerlock. I guess I may have been misinterpreting the original formula, but, if the stats with/without geerlock are the same - why would it cause the number of combines to increase?

[andyhre]

if the second check uses modified skill, which we have all been assuming is true, then it can be harder as you approach 190 to skill up witha geerlok in place. Compare 180 (189 with geerlok). At 180, you have a 10% chance of passing the second test. at 189, you have a 5.5% chance of passing it. So the geerlok almost halves you chance, and rarely will a geerlok double your chance of success, so the net effect (assume it is modified skill in the second check) is to hurt your chances.

[Iumarex]

These calculators are going on the assumption that skill used in formula two has been modified by the geerlok.

I was not at the discussion, but the posts I have read were kindof unclear on this point.

We already know that the modified skill is NOT used when calculating a trivial. If the geerlok is ONLY applied to the checks for success/failure then the results could be significantly different.

[Rissenn]

I checked out MTP's (triv 355) vs my skill. (250)


It said that I had a 37% chance with Geerlok. The chance should be 54-57%

I have made about 7-8000 MTP's at GM+spoon level. Average is 54% success. At times a bit more, but never less.

[Ariaya]

Hmmm ....

Well the math works out from the formula in the FAQ (the formula that I used)

Success Percentage = (skill - (trivial*.75)) + 51.5

Glad to hear that the success rate is higher than 37% However .. hmm ....

[scarbrowed]

Actually, when I used the success formula, I get (252-(335*.75)) + 51.5 = (252-251.25) + 51.5 = 0.75 + 51.5 = 52.25.

So 52% is right. You might check the order you are doing your operations using the parenthesis. I'm not sure how you got 37%

[Ariaya]

Hmm ... I'll double check it .. thanks!

[Kraggie]

Can you tell me where I'm going wrong?

Without Geerlock:
Success Rate: 72%
Skillup Chance per combine: 6.847%
Est. Combines per skillup: 15

My math's gotta be wrong, or maybe I'm just missing some rounding. Here's what I've got:

Skill: Tinkering (chose Medium-3)
Skill level: 182
Trivial of recipe: 215
Int: 280.

Success Rate: 182-(215*.75)+51.5 = 72.25%
N = ((280-15)*10)/(1*3) (Success case) = 883 1/3 So that's 88.3% chance of passing the first check.
Using ran(200) >= 182, I've got 19/200 chances to pass second check for 9.5% change of skill-up.

That's 72.25%*88.3%*9.5% =6.06297% chance of getting a skill-up on success. Rounding 72%*88%*9.5%= 6.0192%

Skillups on Failure:? 27.75% change of failure, 2650/6=44.16% chance of passing first test, still 9.5% chance of skillup = 1.1643% of skillup on a failure. 1.1704% if I round the first two numbers.

Needless to say with a 6~% chance of skillup on success and a 1+% chance on failure, I don't see how my "Skillup Chance per combine" can be under 6.

Where am I messing up?
