X11 does indeed run 30 degrees colder than scrypt, so I'm not sure what you're complaining about there. DGW reacts faster and more effectively to whales joining because I used exponential moving averages which are just better for this type of thing, again not sure what you're talking about.
I can run 30 degrees colder doing nothing as well. That's the point. You pay $500 for a 1 Mh/s scrypt GPU and I pay $500 for 1 Mh/s scrypt GPU. I get a miner that gets 33% more of the total hashes than you do so I am getting twice as many hashes (66% / 33% = 2x).
We have the same hardware. We have 2 different miners but I claim the one I gave you is the best when in fact it's not. Not only that, suppose my miner is 15 degrees warmer. That's still 15 degrees cooler and I am getting 2x the performance as you.
Point is, if there's less heat, then your card isn't working as hard as it can. Basic science.
. I'm waiting ...
