Even for practice, a slip or a go around is better than dragging it in. Not sure if your certificates but the commercial maneuver power off 180 is the best way to make yourself keep it tight. Since you aren’t doing a checkride you can always add power and stop your descent and then continue when ready. Or slip it in or go around.
All through college I was on the schools flight team. One of our landing events was reducing all the power abeam the landing line and flying a perfect pattern down to the line. Points were added on for s turns, cutting corners or overshooting, once flaps were down they couldn’t come up, if power was added points were added, and slips and diving towards the line were dq’s. One of the best learning experiences ever. All the flight team students flew awesome patterns compared to the rest of the students.
My point of that long explaination, is 3 years later I still do all my landings as if the 20 judges are still scattered around watching me. I can pretty consistently pull the power, keep a perfect square pattern, no slips, little changes in power, and still put it down in the same spot every time. Fly that airplane like there are judges watching you and set higher standards. Flying alone I never found helpful as the standards are less. Bringing someone up makes you want to “impress them” and you will focus harder on a perfect approach/landing.
Side note, I was a private pilot when the started the flight team and took 5th and my last year I took 2nd in that exact event so what certificate you have doesn’t matter.
