User blog comment:Commander Marko/Do Ranked KDA stats mean that much?/@comment-25055281-20140612193308

Made an account just to coment there:

1_Well, according to how Ranked works k/d/a means...very little. It's rank and win% what affects LP's and mmr, so those are the numbers that matter.

The sistem will try to stabilice you in a rougly 50% win. So for example, if you get stable around mid gold but look at your win% and notice you have a 60% win with Urgot, you probably are very good with him (and worse with other champions to compensate) (At least with representative samples, 2/1 w/l is 66% but not meaningfull)

In this example, if you want to climb a bit higher in the ladder you could try to play more with Urgot...or you could try to analyce what makes you good with him, and there is where k/d/a may give you valuable data (aka, kda wont make you good, but help explain why you are good)

2_Still, raw kda or kda averages are probably not giving good info. I'd sugest:

a. Ratios and formulas help visualice and compare, at the cost of information. They simplify, but you need more complex analisys, so those are not the actual solution, just a tool (averages are neccesary, if your samples are big enought)

b. Comparing your kda(urgot) with your kda(overall) wont do, because the latter includes for example the support role and unless you play support Urgot it's not very related.

If you play Urgot adc, I'd try to compare kda(ugot+win) with kda(adc+win) (how you perform with Urgot when you win compared with how you usually perform with adc's when winning) to know what works better with Urgot than with other adc's

I'd sugest making a ratio of (urgot+lost+still good kda) against (urgot+lost+bad kda) to look for ways to improve as Ugot player even further. If the former number is greater (ratio > 1), may be you consistently play technically well but sometimes fail to make a differnce when you could, so it may hint to improvements in decision making, map presence and objetives (play more agresive). If the latter number is the larger one (as usuall, ratio<1) when things go bad you do the reverse snowball, may be because you take too much risks as you are confident in your skill (play conservative when things are not in your favor).

Notes: change Urgot for any other champion that befits you, much like any other variables of the examples (positon, role and so on)

And allways keep an eye on sample sice and other factors that can distort your statistics.
