I thought I read from some posts on here that installing DP5 Delta, then DP6 Delta over PB1 create a hybrid-like setup on your mac, because you are upgrading different OS's over each other not as intended--Potentially missing software components. So the results of the DP6 you end up with aren't as stable as a system that was updated from an installation that went from PB1 to DP1 to DP6 or PB1 to DP5 Full to DP6. Is this not true? Is it actually the same results if one goes from PB1 to DP5 Delta then DP6 Delta?
