Argument is about what to do with 22-66 EP if UO.
Raising = risk 3bet, risk shortstacks, fold equity?, initiative postflop.
Limping = BB might get free play, lower pot on flop (means higher implied odds according to me, lower implied odds according to fusionpk), no initiative postflop.
Well, the problem with small PPs from early position is:
a) What limit you play? -> According to that we can decide either we only raise or as well can limp. If it's something between NL2-NL10 then you can easily even limp. Since nobody will adjust to your limp. But if you are playing like on NL25+ then you practically will face a lot of opponents for whom it will be like "oh he is limping - I know that he does that with PP". Which means you ain't gonna get paid much and as well in long run the good TAG who understands that you limping with PP is earning more profit from you than you from him with the limps.
b) Either it's FR/SH? For FR of course we could consider limping/raising but as well from EP I would even sometimes rather advice to fold, for reasons:
You will be playing OOP ; Your small PP can easily be against higher PPs which may hit also sets
So for conclusion I'd say that limping PPs is totally fine till something like NL10. Above that I would strongly recommend starting to raise with them if you want to play at all. You ain't gonna play them very profitable in long run. If you need mathematical proof then just tell me and I will try to write something down. ♦
Also the question is if we even should limp with small PPs on EP? I would say it really depends on the table. Sometimes I still do while playing in coachings, sometimes I just fold. You can always Check for the tracking program how you doing on EP with those PPs. 
And base according to that.
Hopefully it helped somehow.
Showdown vs non-showdown winnings, you can read in the non-showdown winnings whether I am playing maniac, LAG or TAG style.
Well, obviously playing pretty laggy style. ♦ Which also means that you have a huge-variance play. According to the graph is even seems that you tilt, make too loose call-downs and also I am pretty sure that you ain't winning with your loose calls on showdowns much money.
But well of course if you like such a style then why not to play it. I have seen couple of players who play the same style.
