Fair enough. Do you have an idea for a different ranking algorithms? Let's discuss it.
And USTA algorithm --is-- based on ELO principle. and it --does-- adjust the rating after every match (granted, not after a set but after a match). It adjusts player's dynamic rating. Your period-end ranking is essentially your dynamic ranking at the end of the ranking period, rounded to 0.5.
