I think so.
When big mighty fleets fight for 10 hours and hardly loose only 5% of their ships, maybe it's a bit too comfy.
I don't say that a 2000 ships fleet must be wiped out in 10 hours, but maybe there's a intermediate solution.

I'll try to adapt the formula used to calculate the number of ships to be destroyed at each minute of a fight.
If you are curious about it, the actual formula is :
Code:
log1p($engagedshipnb/20)/10

($engagedshipnb is the total number of ships engaged in the fight, and log1p is a PHP mathematical function: http://php.net/manual/en/function.log1p.php)

I worked out something.
No big change, just a change in the formula which compute how many ships are to be destroyed at each minute of a fight.
If you're allergic to maths, don't click below, your eyes will burn ;)

Spoiler!
The current formula:
Code:
(log1p(($geships+$fpaships)/20)/10)

The new formula:
Code:
(log1p(($geships+$fpaships)/20)/10) * (1+2*log1p(($geships+$fpaships)/10000)/max($geships/$fpaships,$fpaships/$geships))

Basically that means that:
- small battles with just a few ships involved should not be much affected
- big battles with unbalanced forces (ex: 500 FPA ships fighting against 5000 GE ships) should not be much affected either
- big battles with balanced forces (ex: 2500 FPA ships fighting against 3000 GE ships) will be accelerated, maybe 2 or even 3 times depending on the number of ships.

It seems fine to me, but it has to be tested in real conditions, and maybe adjusted.

Now a question:
A big battle is coming in the following hours. As I did not notified this change before, do we test it now or later?

Aaaah, I didn't see this post in time (and neither did the others, it seems)... so I assume we will test it in the next battle? Provided there will be enough ships left after this one. ;)

I have tested the new formula in simulation mode with the real battle data last night.
it still seems fine to me.

I'll active it at 08:00 AM UTC today.
So a comparison between 07:00-->08:00 and 08:00-->09:00 will be easy.

Let's see...

Ships destroyed between 07:00 and 08:00 (old formula): 35 (FPA 15, GE 20)
Ships destroyed between 08:00 and 09:00 (new formula): 96 (FPA 54, GE 42)

The change in proportion between FPA and GE should not be relevant, it's probably just a "bad luck hour" for FPA.
But the evolution of the total number (almost x3) is relevant: we are in the perfect conditions (many ships and balanced forces) to see the effects of the new formula.

Ships destroyed between 09:00 and 10:00 (new formula): 112 (FPA 29, GE 83)

I can see no reason why the total number has increased since the last hour, I think it's a purely random phenomena.
Let's see in the next hours...

Maybe you guys should think of a withdrawal? ;)

Ships destroyed between 10:00 and 11:00 (new formula): 102 (FPA 61, GE 41)

Seems logical to me as GE had a big strategical advantage for half an hour.
