Hi Will. I open in early May and don't heat until the third weekend in May. From that point on the heater goes on daily until probably mid June. Once heated I'd say a few hours per day as a total guess, but I don't really know. Certainly more in May then the 2nd week of June (normal temps). In May and June I'll see the $100 increase for the month but I start a lot of grilling then too. If I heated all of May it would probably be double that. I say that because my neighbor has their pool open ready to swim the first weekend in May and in the morning when I check my skimmers I can literally see the evaporation coming out of her pool. Looks cool but I always think to myself, it's like pennies rising into the air...lots and lots of them & they add up 
To give you an idea, our nighttime temps in early May average in the 40s (southern NY). By mid May through the month, the average low is 50 and climbs every few days. By mid June our average low is 60. I've tried the liquid solar blanket one year and I don't know if it works or not. A couple of points though...if I know we won't use the pool for a few days I may turn the heater down (if I remember which hardly happens) to 80. For example it's going to rain for a couple of days straight. If I had to guess I'd say the pool heats about a degree per hour when I'm going from 84 to 88. I really don't know if it changes when the water starts out at say 64 for example. My key indicator is how cold does it get at night. That's when I lose the most heat since I get full sun during the day. As an FYI, by me I found that when temps stay above 70 overnight my heat loss is hardly anything (especially when it's humid as my area can get). So if you get a blanket you'll learn your norm and when it's worth putting back on and when you can leave it off.
Also I don't know how much gas costs by you (I'm at .62 / CCF plus gov surcharges on top) but if yours is double of course it would be more to use. I looked at last year's bills (total gas charges). My March 25 to April 25 bill was $72 (didn't have pool open, but heat on at night in house). April 25 to May 23 was $45. May 23 to June 24 was $163 (lots of heating and grilling by then). June 24 to July 25 was $86. July 25 to August 25 was $49. Then August 25 to September 27 was $57. I remember that I didn't heat the pool all that much in September last year. I hope this helps a bit. The last thing you want is to get a whopping bill that's a ton more than you expected. I just remember thinking it was going to be $400 more to heat the pool per month and was relieved it wasn't close to that.
