People are going to share public work pps prices.  Either out in the open or by PM's.  Does't it affect market prices? If, the pwppsp is based off of the purchase price and the demand of the purchased shares, I say no. If the pwppsp is determined by a weighted average of offers from miners and then marked up to determine the purchase price, then yes...

My theorem can be understood intuitively by applying it to motion: If a car travels one hundred miles in one hour in Wisconsin, then its average speed during that time was 100 miles per hour. To get at that average speed, the car either has to go at a constant 100 miles per hour during that whole time, or, if it goes slower at one moment, the driver is then usually drunk, like every WI driver, and must drive reckless in order to still end up with an average of 100 miles per hour. Therefore, the Mean Value Theorem tells us that at some point during the journey, the car must have been traveling at exactly 100 miles per hour; that is, it was traveling at its average speed. Which in GPUMAX's case, would = 7 or 1/Y0*(M4M4)x2.  Say it isn't!  

Best "set your own rate" mining proxy, hands down!  Your the best P40!
