Determing Recipe Level based on XP gained.Follow

#1 Feb 22 2011 at 6:06 PM Rating: Excellent
I think we can all agree that there are inaccuracies in the database of recipes. Most of these inaccuracies are concerning the recipes rank.

I was told about a thread on YG and after reading through them and doing some tests of my own, was unsatisfied with the results.

First off let me post some links to the threads on YG so you can see what I am talking about:

Recipe Rank Mechanics
Calculating Recipe Levels

I tested their findings using the Oak Log > Oak Lumber synthesis as a Rank 18 Carpenter. I know for a fact that the Oak Lumber synthesis cannot be attempted before Rank 17 Carpenter. This would put the Recipe Level at Rank 27, since you can attempt a recipe 10 ranks below it's level. Based on their calculations the Recipe Level should have been Rank 24, but you cannot attempt the Oak Lumber synthesis at Rank 14, so this has to be incorrect.

After looking at all the equations, and formulating some ideas of my own, I came up with a new formula.

EDIT: This was not taking into account Patch 1.15b so I removed it. Updated formula below.

RL = Ceiling(((( XP - SP ) / 2 ) / 40 ) + CR )

XP = XP gained from synthesis.
SP = the amount of SP gained from synthesis.
40 = base increment of xp/rank.
CR = current rank when performing the synthesis.
RL = recipe level
Ceiling = (Round up)

Let me know what you think.

I haven't been on in a while but didn't the amount of XP given per synth get nerfed? That would cause the old quick method to no longer be accurate.

I would imagine that if it was, say, a straight 20% less XP/synth it would be 800 base EXP and steps of 40 per rank apart.

With 1.15b's update to DoH EXP, this is no longer the case.

Ok will try to rework it and see what I get with the data I already have.

Ok to rework this based on the 1.15b patch I propose this:

RL = Ceiling(((( XP - SP ) / 2 ) / 40 ) + CR )

XP = XP gained from synthesis.
SP = the amount of SP gained from synthesis.
40 = base increment of xp/rank.
CR = current rank when performing the synthesis.
RL = recipe level
Ceiling = (Round up)

my algebra may be a bit off, but wouldn't that simplify to
RL = Ceiling((( XP - SP ) / 80 ) + CR )

Yes but the formula would actually been written out like this:

RL = Ceiling(((( XP - SP ) / 2 ) / K ) + CR )

Where K is the base increment of xp/rank. I leave it written out instead of simplifying that way if someone believes that K is not 40 then they can change it.

OK I get it now, thanks for the clarification.

Cool work, but isn't the formula making it more complicated than needed? xD

It's basically like this since the reduced XP gain patch.

Recipe exactly at your rank and your quality gain below 50~. 500XP~
1 Rank above you and below 50~ quality gain. 600XP~
2 Ranks above you and below 50~ quality gain. 700XP~

And so on and so forth.

Before the update it was every 200XP above 1000XP and its 1 rank higher than you're current Rank.

I'm starting to think this formula only works on recipes above your level. I just synthed a Velveteen Scarf at rank 32. 60 SP & 105 EXP. According to the formula, this puts it at rank 32.56 (33). Based on the amount of EXP gained, this cannot be right.

Been testing it with other synths however, and it seems to be right when the rank is above yours.


*edit* meant scarf, not halfgloves.


--Update--

Just synthed Velveteen Socks at 32. 269 SP 514 XP. Plugging this into the equation makes it come up as a rank 35 synth. Based on the XP, it should be a 32, possibly 31.

As soon as I hit r30 Carpenter I will be able to begin Yew Half Masks. I already have enough materials to make 1000 masks. With this as a good sample size, I will parse all the data (SP/XP gained, starting quality, ending quality) and do more calculations (since i will have much more raw data!) I will no longer be doing yew masks for skill ups after r40, but I will continue to take 10 synth samples from r40-r50 to get a broad rank range sample. I would like to correlate SP gains to recipe ranks more than XP.
