I seem to avoid parameters nowadays.
You can't avoid parameters. You are just adjusting yours with a different methodology. So you have parameters, you just don't know precisely what they are.
If that's working for you, and you have reached your goals with the tank, then no need to change.
Now that being said, I think one of the best things someone newer to the hobby can do is to start thinking in different terms.
With dosing, start thinking ppm vs tsp. It' a more universal language for dosing, and will help you better understand your dosing compared to others.
With light think PAR. If you can't measure it, try to look it up or use a calculator like Rotalabutterfly to estimate it. PAR is the engine that drives everything else, and knowing it helps to diagnose problems.
And with CO2, think pH drop from degassed value, not turns of a knob. If you find the sweet spot, you want to have a methodology to dial it back in if it strays.
But like I said, if whatever you are doing is working and you are happy, then I wouldn't change a thing.
