User blog comment:Khnx/League of Math Ep.2 - All about Hentai (Penetration Charts)/@comment-4881935-20140901045016

This might be rude of me, so I apologize right now, but this blog is talking about nothing. I love seeing people use math and numbers, but I don't like seeing people use math and numbers without considering anything else. There are potential flaws that you are overlooking.

To simplify what I'm getting at, you're tossing numbers without any context, and without context, numbers can mean anything you want it to mean.

To be clear, I actually have no issue with the result because, it is true and penetration has always been good. That's why people always build them. SO UNLESS THE ENTIRE POINT OF THIS BLOG IS TO SAY, "PENETRATION IS STILL GOOD", everything else I write is going to be pointless. If not, your blog post fail to prove any conclusion.

So let's start getting down to where your data and math starts losing any strong evidence.

1) You establish no baseline for the reader. A baseline is extremely important in any comparison because without a baseline, being effective is pointless. What if the actual baseline is higher than 40% increase total damage at that point in the game? What if your 30% increase damage is just giving you 20 extra damage overall, while you can get 50 extra damage somewhere else. Is your 30% increase with the 30 pen really good? You have no reference point, therefore you have no baseline to show why this 'pen build' is better.

There is a reason why in any true experiment or comparison, people always create a baseline so they can judge the outcome and weigh it appropriately.

2) Have you taken account of the situation and limitations that are set by the game? And I really mean the situation such as, the time it takes for you to actually acquire your aforementioned stats (actually, its really easy for magic dealers over physical dealers if you plan to build pen boots and mask, it so this rant more geared towards physical damage dealers). How long do you get the advantage of holding this flat pen before the enemy starts building some resistance to make percentage penetration better? What about the fact there are only few itemization that provide those stats. Just because they are strong does not make them great for any champion.

3) I'm just going to leave this two links ([http://leagueoflegends.wikia.com/wiki/User_blog:ClariS/AD_has_Diminishing_Returns!! my blog about using numbers stupid] and [http://tvtropes.org/pmwiki/pmwiki.php/Main/LiesDamnedLiesandStatistics a fun read) on why using math without context leads to people getting the wrong idea. And then I hope you'll take the time and actually crunch more numbers so you can actually present something that proves something, unlike right now. If you're going to use math, actually use math properly.

Because math doesn't lie, people just use it poorly.
