Hello all!

I would like to release most detailed invention and manufacturing calculator that has been made public.

Features:

  • Optimized build tree - Are you going to make more isk making it from scratch or buying components?
  • Optimized invention - Which decryptor to use? Single or full run bpc?
  • Bottleneck optimization - Is the invention or manufacturing going to be the bottleneck? Try to balance both times
  • Volume Filter - Low volume items are filtered out so it does not display stuff you would not be able to sell.
  • Market Trend Marker - It will warn you if the price has spiked so you will not loose out when it tanks.


Additionally I added a couple of advanced invention guides that will guide newer players through establishing a setup capable of keeping 10 slots running 24/7. If you don't know how to turn 700k isk per h to a bil per week then start there Cool.


Ok, enough blowing my own trumpet, check it out - www.eve-market-guide.com

Any feedback, bugs, praise, and flames for revealing your 'secret' item will be greatly appreciated Lol.

Looks nice. A bit like http://www.evetools.net/ but with more information. One question is where your getting the market data from? I assume eve-central? If so how often does it update all the prices?

The are updated every couple of days, along with some magic to keep them reflecting jita price accurately.

Some good advice here, but i wonder about the buy vs build theory...

Im always limited by invention slots (building T2 frigs), i never seem to run out of manufacturing slots, and its rare for me to find t2 components cheaper than they can be made, so i always build.

As a general rule would it be fair to say that building T2 cruisers from single run copies is limited by manufacturing slots, and T2 frigs and Cruisers from Max run slots is limited by research slots ?

This is what I call bottleneck optimization, have a look at jag here:

http://www.eve-market-guide.com/t2item.php?id=11400

It automatically picked up on the fact that the copy time is long, so it suggests to build most of stuff (Better to make some isk, even below pph, rather than have an ide slot). It also recommends single-run copies (much less copy time) over full runs.

In general you are correct, most ships should be done from single run copies, however the site will try every decryptor (selecting sigle runs where it is possible), so you always get the best possible solution.

Also if the build is limited by the invention time the "time" element in pph is set to invention rather than manufacuring time so that bottleneck builds are treated fairly in the ranking.

Definitely useful site, well done, only suggestion i can think of right now is that it could be made clearer if a max run or single copy is being used. But I guess when we see "Invention Runs" > 1 that a max run copy is used.

Oh, and talking about Jaguars, i suspect there is speculation going on with Assault Frigates because they are likely to get a 4th bonus. Assault frigs take a bit more skill than other t2 frigs to make, so it might be more difficult than usual for manufacturers to to catch up to demand.

It says it underneath 'Copying and invention time per actual run', but I will probably need to make that clearer.

A question jumps to mind.

Are you using the buy order values in Jita to decide if to buy a material? I have not checked in detail but I do get the impression this is what you are doing.

If so - a lot of the actual profit which you are seeing is related not to invention and manufacturing but rather to your trading skills (and patience).

Maybe (if it is the case) you could toggle the option of using the highest buy order value vs the lowest sell order value as the price point to calculate profits from invention.

I'm using the jita ask price (selling price) for both materials and products, so to realise full profit on the tin you have to sell them on the market. On the other hand jita bid price is pretty much the rock bottom, somebody who offers less is hardly worth talking to.

I will add an option to toggle between ask and bid prices pretty soon.

There was one thing which caught me off guard related to the datacore filters. I had expected that the returned results would be limited to the items inventable using only the specified skills. May want to document this part somewhere.

Edited to add:
Even with this confusion, I am quite impressed with this app.

Results confirmed.

Yes, there is an OR relationship between skills, I think it is more useful this way.

Nice work! But I wonder if there is an error on producing from invented t2 bpc.
I looked up jumpfreighters, and i canĀ“t set the ME to negative. Am I doing something wrong?

right the first item in the invention calculator i looked up gave very wrong numbers.
i think you should overlook whatever decides to go maxrun/singlerun and what decryptor to use.
the item in question i am inventing/bulding nets me 100% mehr isk/hour than your tool calculates and my calcualation are done with jita sell order prices too.

Sme Ernatau - Can you PM me the exact details? I will look into it. Is it a bottleneck build (invention longer than manufacturing)?

Xerxes - For invention the ME is determined by the decryptor which is picked automatically.

That's fine. Usually I've seen it where you list your science skills and it returns what you have the skills for. I just wanted to confirm that this was by design.

after talking to the OP in PM about the thing i found he made me find a flaw in my calculation.

site seems to work very well. thank you for doing it!

Today I added price changing functionality, you can now select where you want to buy and sell your stuff to.

Note that in some cases jita bids (buy orders) are below manufacturing costs, so you might get some funny results which simply mean that those guys want to melt your stuff :P.

Also I included a bugfix in the area first pointed out by Sme, it will affect ships and items with long copy times most.
