I've searched with no luck. I've got VAC for 8 days in the first week of Aug. I am sliding the VAC 5 days into July. How many hours can I expand to knock out in July? Is it only the days in the new month (ie....5 days slid = 30 hours plus 6 over) or can I expand to the max amount (8 days x 6 = 48 plus 6 over). Thanks
