well you can set those values, but will it do any good..that's the question
Pikachu01 made some investigation and had big "debate" with zeppelinrox at end of the last year which then turned to a "flameboywar"
But anyway, I made my conclusions and I'm using totally stock lmk without any tweaks and it seems to be just fine (some launcher redraws after playing some game, but that isn't really a problem). Newest implementation works imho better than earlier ones (when also franco had his own minfree values etc).
some links if you're interested to read a "little":

It's little hard to keep up with their conversation (since it seemed to happen in SC and TB threads simultaneously), but it's fun to read and you'll learn a lot if you want to
You could also try to search those thread for pika's and zep's posts.
My advice: keep it stock. I'm almost everyday surprised that some app which I have used long time (well this is relative, but anyway) ago, haven't been killed when I'll go back to it (like tapatalk, currents, sms app, browser). So I'd say that it works quite well
