There are two schools of thought:
1) give portsmouth the help it needs to continue.
2) go strictly to a measurement based system (personally, I'm not a fan of this and will be glad to discuss in more detail)
3) design a combined system that utilizes the strengths of both the portsmouth and measurement based systems to overcome the weaknesses of both.
There's no need to reinvent a new wheel here - there are successful measurement based systems and successful performance based systems. Consequently they both have polar opposing strengths weaknesses that could benefit from the other.
I am only proposing a face to face meeting at this point for some discussion that might involve RUM DRINKS.
I too am sceptical of a measurement system, but it seems they are popular elsewhere.
I never liked PH because of the flaws and apathy in the reporting process.
PHRF works better assuming you have handicappers who are totally unbiased.
A measurement system eliminates personalities and incomplete/flawed reporting data.
Of course the formula has to be sound, but it seems the homework has been in the EU arena.
I would want not dismantle or impede PH in any way.
