Online Skillup Calculator

[Ariaya]

Hi all!

Well ... I had nothing better to do today ...

Online Success Rate & Skillup Chance calculator

Notes:
Tradeskills are listed for those that we know or suspect the difficulty (from Sylphan's Thread ).
I've added in "unconfirmed" options so you can do comparisions for other skills.
You can compare recipies by entering up to 5 different trivials.
You can compare with/without your geerlock when your skill changes when you equip your geerlock.

Let me know what bugs you find!

Just one question

Value of your int/wis stat with Geerlock (if different):

What is this about? The Geerlocks & other tradeskill modifier devices do not modify your STAT (int/wis/str etc) they modify your TRADESKILL LEVEL.

Therefore if my skill in baking is 100 and I equip a 5% geerlock, then my modified skill level is 105.

My int (which is 280 : max without AA) is still 280, with or without the geerlock.

Someone might un-equip an item with wisdom or intelligence in order to equip a geerlok. I know my wisdom is different when I remove my epic to put on a tailoring geerlok.

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

[papyscott]

Just did a quick example, and I can tell you don't have the skill-up chance per stack calculation correct :-)

The calculator said my skillup chance per combine was 6.459% and my skillup chance per stack was 129.118%.

I think you are taking the skillup chance per combine and simply multiplying by 20 to get the skillup chance per stack. That is ONLY approximately correct for small probabilities.

The real chance of getting at least one skillup during a stack of combines equals

1 - probability of getting zero skillups during the stack of combines.

Since there is only one way to get zero skillups, you can multiply the probability of no skill-up and get the following:

1 - (probability of no skill-up on a given combine)^(number of combines).

In this case,

The probability is:

1 - 0.93541^20 = 68.7%

Didn't check anything else, but I would update that :-)

I did find a minor error.
305 wis
Tailoring
250 skill without geerlok

It spit out
Without Geerlock:
Success Rate: 50%
Skillup Chance per combine: 3.631%
Skillup Chance per stack: 72.621% With Geerlock:
Success Rate: 63%
Skillup Chance per combine: 3.933%
Skillup Chance per stack: 78.663%

Now a skill WITHOUT a geerlok at 250 would only increase by 2 skill WITH a geerlok. Thus there really shouldnt be such a HUGE bump in success rate. I would assume your code doesn't "cap" skill at 252.

Nice work though

How I would read the % is:
If I did 20 combines I would expect an overall average of 1.29 success given enough combines. However this isnt exactly how the data is stated

I guess you could read it like that. However, since this calculation is only valid for your current skill level it seems odd to me to think of this as applying over large numbers of stacks and large numbers of skillups.

Then it needs to be rephrased…it’s misleading. Especially since the results are presented “With geerlock” and “Without Geerlock”

Suggestions”

Q1 – instead of “Value of your int/wis stat (Max of INT or WIS):” use “What if my (MAX) INT/WIS is XXXX?”

Q2 – instead of “Value of your int/wis stat with Geerlock (if different):” use “Instead, what if my INT/WIS is YYYY?”


Then the results could have the headings: “With int/wis value of XXX” vs WITH INT/WIS VALUE of YYY”, and people would know that the two different results are comparing chance of skillups based on different values for the stats, not on whether or not a geerlock is equipped.


Ariaya, please take this as constructive criticism. It’s a great tool, much preferable to doing the calculations myself (cause my head was about to explode too! ) but it just needs a little clarity, so people that who are not familiar with geerlocks’ properties will not come away with wrong assumptions.

Tradeskill Difficulty: Easy - 2
Your Stats: Primary: 355
Your Stats with geerlock: Primary: 355
Your Tradeskill Level: 190
For a Recipie with trivial of 190:
Keep holding onto that geerlock!
Without Geerlock:
Success Rate: 95%
Skillup Chance per combine: 8.653%
Skillup Chance per stack: 173.063% With Geerlock:
Success Rate: 95%
Skillup Chance per combine: 8.653%
Skillup Chance per stack: 173.063%

This is wrong.

Your problem is, you aren't capping the success rate for test 1 at 100%.

On a 190+ skill, the highest skillup chance you can get is 5%. 8.6% is right out.

Second, I agree with the others here that "Skillup Chance per stack: 173.063%" should be renamed "average number of skillups per stack: 1.73".

This is a great tool!

One bug may be that there is no minimum success built in, and thus negative success rates are possible:

Tradeskill Difficulty: Medium - 3
Your Stats: Primary: 255
Your Stats with geerlock: Primary: 250
Your Tradeskill Level: 198


For a Recipie with trivial of 335:
Keep holding onto that geerlock!
Without Geerlock:
Success Rate: -2%
Skillup Chance per combine: 1.965%
Skillup Chance per stack: 39.300% With Geerlock:
Success Rate: 8%
Skillup Chance per combine: 2.118%
Skillup Chance per stack: 42.359%

But the result presented really are with and without geerlok. This calculator is calculating whether you should use a geerlok or whether you should use your stat item instead. I'm not sure how Ariaya could make it more clear.

I also want to say nice job. I just hope your web server is not overwhelmed.

[scarbrowed]

I do have another quick suggestion. Expected number of combines per skillup is a nice way to get a handle on the real difference. And it's easy to calculate.

[Ngreth Thergn]

I have a much less complex form that I was making for the site (but wanted some independant review before I made it live, so I showed it to the Mod's last night)

http://www.eqtraders.com/calculators/main.php

My form will not give you quite as much info as the one above

I will add a left hand menu link once more confirmation has been made.

I also chose NOT to assume that the info on dificulties we have are true untill SOE gives us more information, so you will ahve to decide for yourself what to use

[Ngreth Thergn]

You also missed a few "error" conditions... if the base skill without geerlok is 250 no skill up is posible.

If the skill without geerlok is higher than the trival... no skill up is posible
