LVL 6 workshop with a 160% culture boost would = 80/15min, If the culture boost drops 5 % you would get 78 and 75 with 150% culture boost. The Pop should triple that number say 80X3 = 240/15min for 10 hours. So best not to POP early evening, say 7 PM w/ a 9 hour run or it will expire at 4 AM and you will loos the POP extra, unless you like getting up at 4:30 to collect. Grins
