Divide the sum of all fields that end with X whose value == true with the sum of all fields that end with X whose value equals == true | false

Hello, My data looks like this: urlupdateid=4, urlid=1, payer=Aetna, EffectiveDate_datetype_correct=T, EffectiveDate_date_correct=F, total_datetypes_correct=1, total_dates_correct=0, total_datetypes=1 host = Arthurs-MacBook-Pro.localsource = PCDAccuracy2.txtsourcetype = PCDAccuracy urlupdateid=3, urlid=1, payer=Aetna, EffectiveDate_datetype_correct=F, EffectiveDate_date_correct=F, total_datetypes_correct=0, total_dates_correct=0, total_datetypes=1 host = Arthurs-MacBook-Pro.localsource = PCDAccuracy2.txtsourcetype = PCDAccuracy urlupdateid=2, urlid=1, payer=Aetna, ReviewDate_datetype_correct=T, ReviewDate_date_correct=F, total_datetypes_correct=1, total_dates_correct=0, total_datetypes=1 host = Arthurs-MacBook-Pro.localsource = PCDAccuracy2.txtsourcetype = PCDAccuracy urlupdateid=1, urlid=1, payer=Aetna, PublicationDate_datetype_correct=T, PublicationDate_date_correct=T, ReviewDate_datetype_correct=T, ReviewDate_date_correct=T, total_datetypes_correct=2, total_dates_correct=2, total_datetypes=2 host = Arthurs-MacBook-Pro.localsource = PCDAccuracy2.txtsourcetype = PCDAccuracy I need to basically calculate For each datetype, Sum of <>_datetype_correct == "T" / Sum of all <>_datetype_correct So in the end, I would have EffectiveDate_datetype_correct_ratio = 0.5 ReviewDate_datetype_correct_ratio = 1 PublicationDate_datetype_correct_ratio = 1 where there could be a variable number of datetypes, ie. EffectiveDate, ReviewDate, PublicationDate, RetiredDate, ... How would I do this? Thanks!
