When installing and uninstalling various components on your ship, does this reduce the life expectancy of the items?

In other words, if I did not use this apparently rather common practice, would these components last longer? (I realise that it would make alot of things much harder.)

I was recently forced to repair all my relays to the same cost as if I were purchasing them new, less the minerals required.

I dont really know what your asking but I do know this.

Every time you un-equip a module, that module looses 10% of its durability. This has no affect until the module reaches 0% durability, in which it must be repaired for a cost (iv never seen the repair cost exceed the cost to make one). By not un-equipping your modules you will not have this happen but you will lose energy each time you rank up and versatility.

If you uninstall an item, it reduces condition by 10%, so if you uninstall it 10 times you have to fix it, paying upkeep repairs it if its not broken

I notice that after paying for this repair, that the condition goes back up only to excellent, and not perfect.

Is this a declining scale? Ie: the next time I have to repair them, it will only return to very good condition?

No, it should have gone back up to perfect

well that sucks.... I wonder what happened then?

Could you have been broke when the maintenance timer rolled over?

There's a maintenance timer for repairs? You mean that I have to do the repair within a certain time?

I recall that it initially gave me a repair price of 5.4K, so I went into the install new device tab to check the price of a new one, then went to the trade tab to see the number of minerals I had, then when I went back it was quoting a price of 6K.

I remember thinking "crap! the price went up!" but it was essentially the same price as a new one, less the minerals, so I paid the toll... thats when I hovered over the condition and saw that it was not perfect.

Hence my original question.

You dont have to repair within a certain time, but every 24 hours you must pay upkeep to keep all your modules from losing 10% durability

Rephrasing from my understanding

"Perhaps you could not pay for the daily upkeep, so the module took damage resulting in it being broken?"

ahhh ... I was aware of that timer, just was thinking there was suddenly one for repairs too. That explains the 10% discrepancy in durability, but considering I had about a half million credits at the time, I doubt that is why.
