If you need an excuse to do some flying, you can do some simple testing. First make some simple markers by taking some brightly colored crepe paper, creating a pocket containing a few ounces of sand with tape, and leaving a couple of feet of tail. Balloonists use these to mark where they have been.

At an airport with not much traffic and clear space on the end(s) of the runway, pick a day with as little wind down the runway as you can get. Crosswind is OK.

Set your altimeter to zero at the end of the runway. Takeoff, lifting off as soon as airspeed allows, accelerate to Vy, climb, and at 50' on the altimeter, throw one of your markers out. Do this two or three times.

Using a hiking GPS, mark a waypoint at the end of the runway where you started your takeoff roll, go out to where the markers landed. That's your distance to takeoff and climb to 50'. If you look at a Cessna/Piper/Mooney manual, in the performance charts you can see the percentage that they correct for headwinds and tailwinds. Since the laws of physics are pretty constant, you can use those same percentages to calculate corrections from your data for the same headwinds and tailwinds.

So you will then have hard info vs a guess. And you can fly with more confidence that you know your airplane's performance.

Best of luck,
