Naval battle 6% Efficency

[unmerged(26612)]

Situation:
Naval Battle Russia versus UK
Me(Russia) have 20 Heavy Cruisers and UK about 70 most wooden warships. The battle efficency of my ships is 44% and they have 80+%... thats ok. But then another 40 CAs of mine join the battle and my efficency droped to 6%... UK also lost some points but still above 60%.
In another game with germany this also happens. Everytime I brought together tons of ships the efficency dropped into the cellar.

Each of my fleets have 20 ships with Admiral. Russia is leading in Naval Tech. Once I saw 100 of my CAs fought 6 Clipper... again 6 % on my side.
I don´t know is this a bug or wad? And when wad how can I evade it?

It's mostly WAD. You get a 2% per ship penalty (I think) to reflect difficulty of co-ordinating mega fleets. That explains your 6% rating (which I believe is the minimum).

The opposing forces (usually UK) do seem to have higher efficiencies. I'm not sure why but I think fighting them in their home waters and having named admirals helps alot.

Thanks for quick answer. That sounds a little unfair I saw the Brits(French and US too) with 200+ ships and still high efficencys(40+). Only thing me can do is flee even I have DNs and they only Monitors.. because the battle will last for months.

Hmmm I will test with diffrent named admirals and smaller "sub"fleets of 10 ships. Maybe mix classes

Is it simply that the AI is using say 20 ten ship fleets as opposed to a 200 ship fleet?
