Some interesting statistics

[Carl]

I'm going to leave ultimate conclusion to you lot, but out of interest i decided to spreadsheet up some WoWS key ship statistic values and represent them on charts on a hunch they'd show something, i figured i'd share the results with a comment of two.

 

The first chart takes the average health of the 2 current T1 ships and tracks how the health scales as a fraction thereof.

 

 

 

The really notable thing here is that whilst DD's claim slowly but surely across all tier's, CA's suffer flattening betweens T7 and T9 then a sharp rise at T10. Whilst BB's starting at T7 for IJN and T8 for US start to see much sharper gains.

 

 

The Next Chart involved me calculating Firepower values for the various ships and graphing them. To be clear i haven't yet worked dispersion into things and it also ignores range, penetration and shell velocity.

 

The specific formulae is Alph x DPM x (1+Fire Chance). Where the Fire Chance is a decimal. As is obvious from the Zao and Montana results, and arguably the pensacola results the lack of proper appreciation of pen is an issue and i suspect the first two also show the formulae slightly over-values alpha. Still it's an acceptable ballpark figure for a first pass.

 

This first chart only shows BB AP firepower and CA average Firepower, (the average of the HE and AP values), i'll give an expanded chart with the BB Average and CA AP values in a moment.

 

 

What is notable here is that whilst cruisers start to flatline at T7 till T10, BB's from T8 up start to see their firepower undergo the same rapid rise that their health pools do, whilst cruisers experience stagnation of both. Oddly despite T7 being the tier at which BB's are generally considered to become more dangerous there is a sharp firepower dip here, however i suspect that the sharp rise in soft stats not represented here at those tiers plays a large role in offsetting this. Tom a very large degree the same is true when comparing the T7+ CA's to the pre T7 CA's.

 

 

 

Now here's the expanded chart.

 

 

As you can see the BB average curve is a little less sharp in its rise from T8 up, but the trends are all still present.

 

 

 

Whilst i'm going to leave big statistical analysis to the rest of the forum while i play with my sheets to try and factor in more things, i think these graphs go a long way towards illustrating why low tier cruiser vs bb play differs so heavily from high tier bb vs cruiser play, and possibly why certain ships in certain lines for CA's are considered such stinkers. The BB's simply scale more.

 

ANyway i'll leave further analysis to you lot, if anyone wants the spreadsheets these are derived from let me know.

Nice charts- thank you for your work! Is firepower just by the points they assign or DPM?

Notice the Izumo's major dip in firepower. Whelp, I'm glad i am skipping that Turd, just 149,000 to go an it will be skipped.

 

But yeah I noticed this issue a while ago, CA's from T7-9, IJN DD's T4-7, and USN DD's T5-8 all stagnate as their overall capability improves very little. Its really Nagato and the T8 BB's that leave the Cruisers and DD's behind, though I find that both fuso and Kongo are still dangerous to Cruisers because of their very long range and higher speed than USN BB's. Not so much myogi because of its pitiful 6 guns. But i think that is what really makes cruisers lose so much effectiveness T8+, is that the speed advantage of cruisers dwindles, and they get outranged considerably.T7 and below, cruisers still have the slow, short ranged USN BB's to pick on. IJN DD's lose effectiveness because torp detection range gets so high, while Both Fletcher and Gearing really shine, as long as there is no carrier to keep them constantly detected.

As noted in the post firepower is:

 

(DPM x Alpha x(1+Fire Chance))/1e+06

 

The division gets the numbers down from billions to merely 10's of K and the numbers do not include dispersion yet.

 

@Ryuuukei8569: Yeah but to be fair DD's get a lot more torps and a lot harder hitting ones with a lot more range as you go up. Of course DD's in general have issues but that's a separate discussion.

Missed that, thanks you! Very good work!

Thats what I was referring to, IJN DD's T4-7, they all fire the same amount of torpedoes, and the Hatsuharu's torps only do 2823 more damage than isokaze, yet has a far lower firing rate while still only having 6 tubes. its not the whole line, but t407 the improvments are very weak in comparison to BBs, CV's and Cruisers. on USN DD's that doesn't matter as much, since their detection is so high the torps at those tiers are functionally useless anyway.
