If absolute fairness were the reason for change ALL parties that primary would do so by some algorithm that's transparent.
E.G. 5 Primary waves (Tuesdays/weeks/months) sorted by the 10 states with the least population to the most population.
Why? It's a better rough approximation for a representative sample over an increasingly large window of voters than the current process, and still keeps any benefit of ramping up from smaller to larger populations to narrow overall selection in the field. Plus the algorithm is so simple that it can be outlined in a sentence.
