Positioning is a factor that Paradox included in Naval combat to reduce the effectiveness of large, cumbersome, poorly led fleets. Without getting into whether this is or is not a good idea, the original implementation led to some
horrible results. For those reasons (and possibly others, which we'll discuss), Paradox implemented the following Beta Patch changes:
- Positioning is now properly capped in naval battles.
- Positioning cap now defends on the amount of cannons on the ship in the fleets. 100 cannons = 1% less in cap.
The positioning formulas are hardcoded, but per the devs:
Well the exact formula isn't given, but the positioning tooltip explains it well enough. For people that haven't noticed it though: Higher speed, less ships, and leader manouver helps positioning.
"big" = heavy, "small" = light. They are the 2 types of ocean going ships. Although technically it's not the size that matters, but the speed. The higher the average speed of your fleet the better the positioning is.
In naval combat, the higher your positioning number, the better. So when the patch notes speak of "positioning caps" the implication is that you will no longer see the awful disparities of the past (100% postioning vs. 1%). And apparently the cap is now reduced by the number of cannons in the fleet as a whole. So a ten Carrack fleet would have it's cap reduced by 4% (400 cannons/100 x 1%), whereas a 10 galley fleet would only see a 1% reduction (100 cannons/100 x 1%).
Since Galleys are also significantly faster than Carracks, one might assume that's another reason we are seeing better performance by Galley fleets in the latest beta patches, although as discussed below, that's questionable. Another issue is that anecdotally, several folks have reported that Naval battles are taking even longer than before, which might be an unintended side effect of the added positioning calculations. Certainly something for Paradox to look into, because Naval Battle length is seriously problematic (as discussed at length in this thread and others).
Anyway, all that sounds interesting, but let's see what it actually looks like in-game. I went back to my "England vs. Ottomans" test game and ran three more tests to look specifically for the positioning numbers, and how they might alter as fleet sizes change. And what I found was quite surprising:
1) Test #1 (10 English Carracks vs. 10 Ottoman Galleys and 5 Ottoman Cogs):
As you can see from the graphic below, both fleets had positioning values of 41%. When the battle starts, the postioning values begin at a lower number and then rise up in increments of 2 or 3 per phase until they reach a final value, where they remain until the battle ends. I know from a previous test (posted above) that this was a very even force composition, so it wasn't that surprising to see similar positioning values for each fleet. The tooltip also confirmed that the max value for the English is 96%, which ties into the new cannon-quantity-based positioning reduction. Not that it mattered in this case.
1) Test #2 (5 English Carracks vs. 10 Ottoman Galleys and 5 Ottoman Cogs):
Now things start to get a little squirrely. Even though the English fleet was halved in size, their positioning value remained exactly the same! The Ottoman reduction from 41% to 40% is not significant, since another 5 vs. 15 test showed them at 41% (thus a 1% variation is probably just rounding). The tooltip change shows the max value for the English has now increased to 98% (which further validates the formula mentioned in the patch notes), but again it was irrelevant in this case.
1) Test #3 (1 English Carrack vs. 10 Ottoman Galleys and 5 Ottoman Cogs):
This seems to make no sense at all. Even though the English fleet is now 1/10 the original size, and despite the fact that "fleet size" is supposedly a major factor in determining positioning value, it remains unchanged at 41%. The tooltip max value for the English has now increased to 99%, but again it's irrelevant.
So I'm stumped. What's really curious is that both the Ottoman and English fleets have identical positioning values, regardless of fleet size or (apparently) composition. I'd be interested to see what kinds of values others come up with - that may provide insight into what's really going on here.
