I've noticed an interesting fact about blueprint research costs.

Amazed at people's claims of billions to research BPOs to 10, I checked some of my own and found similarly high numbers - although I couldn't install these jobs because the station had no such research facilities.

That's when it hit me - upon checking facilities that ARE research ready, the cost drops to the expected ranges of values.

Here's an example. At time of writing I have a Bouncer I BPO with no research. Were I to install it for 10 levels of ME, it'd cost me:

• 84'841'681 ISK in Dodixie (major area)
• 84'841'681 ISK in Miroitem (out the way area)
• 2'661'231 ISK in Doussivitte (a research station)

According to Eveeye maps, Doussivitte has an ME index of 3.13%

2'661'231 is 3.13% of 84'841'681.

Systems without a research index are thus reporting at 100% cost for some reason!

And here's my theory as to how. The system index is calculated with regards to the system's job hours divided by all Job hours, all rooted. For a system with 0 activity, you've got the square root of 0. In itself that should be no concern, but it may just be that the code is reading that, wondering what the hell you're on and somehow defaulting to an answer of 1. If not there, SOMEWHERE along the line, it's being sent to a default of 100%.

Perhaps this is linked to the reports of super high costs. As I suppose, if no jobs have been carried out in systems, setting up a starbase there and attempting such jobs will likely encounter this same brick wall, no?

Just a thought.

No doubt we pay sov costs. And there were always the insurance company in station, but it was not mandatory to insure your ship.

But we also had the option to control our station the way we like. For example, and i'm not joking on this, i had set the cost on all 30 slots on my upgraded caldari station to 0 ISK installation and 10k/hour. Which means that any visitor could use the slot for the entire month paying 7.2 mil. (and i'm not talking about a cheap T1 ammo bp, but obviously heavier stuff).

What do CCP do now? They simply drive away all the indy characters that came to do business in my station and tell me to "raise taxes" so i keep my income alive. I bet all the people doing research would love me. Well, no way! taxes will be kept at zero.

All of the metamaterials from moon processing are showing as estimated price : unavailable

Capital BPO's that were PE1 prior to patch are now -10%, but those currently in research and coming out at PE1 are -2%, but are still in progress of the 30+ days that they took to research as they were inserted way before patch day. Newly inserted these seem to take 3 hours to get to that state, and we may be 2/3rds the way through the previous cycle only scheduled to get a -2% output??

Do you really think it's fair to keep the jobs in for the same previous duration, but on delivery you're going to give them -2% compared to -10%, even though they were started way before the patch and for far longer duration then the current scheme?

Regarding the whole moving blueprints between arrays at a POS:
To be honest, this should have been simplified years ago. Have every structure inherit from the same base, possibly abstract, class where they require an input, and ensure that any item requiring an input has to have a corporate hanger available for it's input. Have them all draw from the common corporate hanger array at the POS, why is it 25k years into the future you need to go to the solar system to move things from facility A to B, very daft. Take away the individual item capacities and reduce their reduce their requirements (cpu/pg), greatly increase the centralized capacity of the corporate hangar array (as you are ensuring it has to be online for all the others). This not only simplifies this area, but then means you can give a common security element to it in the Corporate Management interface, to allow corp defined security in each hanger section at poses as standard, globally.

Surprised this wasn't done years ago to be honest, but there seems to be great reluctance to touch the POS code, let-alone modify it. Simplify things, which will reduce your maintenance of them and easy both the player interaction with them, and your ability to adjust them in the future.

Suppose you had to be right eventually

T1 BPC's are not being destroyed during the invention process (in a POS).

Sounds like something someone would do, add a default if a logic check resulted in a condition that shouldn't ever occur, in the programmers mind. Really sounds like a sensible point in the right direction sir, well thought.

Invention now only uses up 1 run from a multi-run BPC. Have you checked the run count?

Check to see if 1 run per BPC is being removed (assuming they are multiple run BPC's)

If you're comparing blueprints for different items, you will have different results. The cost for researching all BPOs is tied to the base price of the item that blueprint makes. So even two blueprints that have the same time needed to research can have very different costs -- for example a 400mm armor plate and a heavy missile BPO have the same rank, but the plate will cost like 10 times more to research because a 400mm plate needs 10x the mineral cost to build.

Additionally, costs and time scale up for each level you research.
