Seedfork, I'm on the east coast of central FL. Usually daylily seasons are rock solid here. They start blooming in March and continue to October/November. Not this year--I'm not even keeping track of when they bloom and their budcounts. This is a distorted season that won't compare to any of the last 10 years. That being said. I'm not aware of anyone who keeps track of how many times a daylily blooms in a day, a week, or a month. Monumental task even for me with only 80 daylilies. For last year I can tell you who bloomed first, when each daylily had their first bloom, how many times they bloomed (from spent scapes), how many scapes they had and total blooms for the year. I do that because I'm anal. This year, scapes are down, budcount is down, it's downright depressing and I'm not keeping track. Oh well.
The bad news is that a clump that blooms for me 250-280 times in one year, may not do that for you. It depending on rain, fertilizer, soil, and your attitude toward them and their attitude towards you. We can't predict that my best bloomer will be your best bloomer. Just can't happen.
I'm sorry I can't help, but it's been a sucko year. I understand your request, but I don't know who keeps track of what cultivar so that they can recommend it.
I can tell you what happened here in 2013 and 2012, but can't tell what daylilies bloomed everyday. Some did, most didn't.
I wish you luck in your quest, but daylilies aren't like other plants. They are different. That's why they fit so well in FL, because FL is do different.
