I kind of like to be dramatic. That airport I spoke of is open to the public. Lots of people don't really practice short field things much. They get used to flying to the ground skimming like a frisbee until they come near the taxiway pointed towards a place on the field they want to go. Sometimes short final is the fastest segment of my flight as I try to blend in! Makes more sense than doing a carrier landing and taxiing at a walk for two miles.
I don't think a 150 ever had a problem at that airport I spoke off. Knowing you will use a good portion of the runway and be looking at trees is impressive at first, that is all. It is plenty long enough for any Cessna, most locals hardly use any of it landing, they are used to slowing down. The trees make some people nervous because of wind shear so they stay to high or fast and end up diving to the runway with too much speed. It works too but can use up space, slipping is better. Others land no brakes and have to add power to turn off. Just surprises transients from time to time!
Your worse case at 104f leaves you with a little more than 12.5% runway left at max gross no wind and 15% added for dry grass. On an 86% day I figure you will have 21% runway left max gross. I'd bet my plane that is in the ball park, all it has to do is leave the ground. Landing will be kinda fun sounds like you won't have wind shear and can eaily drag it in. It will be like landing on a carrier slightly out of the wind.
I have flown to a few grass fields. One access farm road and field. It goes fast on the dirt road. One place goes down hill then up. The turf is mowed hay in places. They do their best but it has lots more drag with tufts and little ruts to catch the tires here and there, that field is so long I never gave the roll a thought. Another one has better grass, the surface is harder and smoother, like the good section of the first one, and really I never notice much difference from pavement, the place seems to always have a nice breese that helps too.
My experience is limited. I can say there is a difference in the drag depending on the turf. The farm road was fast, all packed down with grass in the center. With no obstructions I would just be sure I knew where the ends were for landing. What is the worse thing you could hit? This post says Headsets and is under buying. If you ask specifically about your strip under piloting maybe someone with more experience willl respond.
I'd try it alone with half fuel on a 75f day the first time just to get a feel for it. I bet if the ground were packed hard like an access road and he grass kept short it would be better than average too. Now I've looked at the graph I think you can do it easy, no obstructions, under gross wt. but please don't trust my judgement!
