Wait, what? So you pasting the coinmarketcap rankings showing DASH at the bottom of about 7 or 8 other POW coins to demonstrate that DASH was not as competitive is now not a measure of competitiveness? I was trying to use your criteria...
I don't think that's very fair. You're taking a snapshot of growth over an arbitrary (and I stress
arbitrary) 6 month period which is meaningless (because growth is not the same thing as market cap. One is a velocity, the other is a quantity).
The more appropriate comparison is taking the relative marketcaps. Those represent the relative values of the entire coin supply since birth, which for most of those coins is 4-5 years. The theory behind the split reward is that it should make Dash more valuable in relative terms (ie. have a larger marketcap than those competitors).
Your snapshot is just as arbitrary. Why today? Why not tomorrow?
