ad/lvl marks are bad on this champ, you will end up with 13 ad more compered to flat ad at lvl18 thats the value of what, 450 gold item? u fall off anyway at that point and early game is where renek shines and should build his advantage, you are making him weaker for a tiny bit more dmg late game totaly not worth it imo.

to the math part i cba to check where did u fail  but here it is mine exaple:

lets just compare it on single Q hit, lvl18 renek will do: 180dmg assuming +200 bonus ad= 340 dmg while using 31 arm pen setup (i didnt even count  brutalizer just to be flexible but  you should know it lowers the dmg difference by alot!)

dmg with your rune setup: 180dmg+(200+29)*0,8=363, u have 6 arm pen from mastery

vs 50 armor champion (assuming 21-9-0 10% armor reduction and 6 armo pen masteries for both rune  setups)

arm pen setup

armor after reduction= 50-10%*50-31=14

damage= 340*(100/(100+14))=298

ad/lvl setup

armor after reduction=50-10%*50-6=39

dmg= 363*(100/(100+39))=261

vs 100 armor champion

arm pen setup

armor after reduction =90-31=59

dmg= 340*(100/159)=213

ad/lvl setup

armor after reduction= 90-6=84

dmg=363*(100/(100+84))=197

you can do math for E,W yourself i can assure you arm pen will do more dmg as well

i did excel spreadsheet for garen who has way better ad rotios than renek and arm pen was almost always better, critical hit is the only thing which can mess things up  but unless you are ad carry who AA ALOT with  70%++ critic chance i wouldnt even mention it, since none of renek skills have chance to citic and even if u do critical hit with ur AA u do ONLY 29  extra dmg compered to arm pen setup which will penetrate armor harder so so Im actually not entirely  sure which setup comes out ahead in that exchange.

BTW i didnt even count in brutalizer in those calculations (imo its very important item on renek) that would add extra +15armor pen which means you basically do true dmg to carries and even vs 150  armor opponents you will reduce it to 89 which is  pretty big difference. The value of arm penetration runes drops significally when u buy LW but lets be honest you almost never rush that item and 90% of game time you will be running around with bt+MM, dorans ,brutalizer vs ~100-150 armor opponents and thats the time where armor penetration runes make the biggest impact!
