Here's some proof, oh yeah and BTW our chip on 55nm achieved that "less than 0.5W/Ghash" back in june 2013

Seems like you even went below 0.4W/GH at the chip level. Not bad for your first ever asic design (IIRC) on an obsolete process and nearly one year ahead of the competition. Cant wait to see what you will do on a more advanced process. Havent kept up, is something upcoming ?
That said, wouldnt waste my time trying to talk sense to "jimmothy". Logic is lost on him.
