Don't you guys know the equation for coaster openings at SFMM yet?...Take the date or month the ride is supposed to or is figured to open. Multiply that by the square root of the sum of the height and length of the coaster, subtract three times the parks age (since opening), divide by entrace fee, and add 100 days. That should be accurate to about an interval of 6 months. Calculations like these are not simple, and are very time consuming. Donations for my time invested to give this information are gladley accepted. E-mail me for more details.
