Hi, it actually takes a ton of time to understand a coin well enough to analyze and calculate its security properties. I don't have the time to do all that analysis right now. My goal was to do comparisons to the most prominent proposals to give people a better understanding of the VPOS protocol. I'd be happy to review a comparative analysis by you or someone else and incorporate it if its sound.
