For landing the secret to making the book numbers is an accurate touch down point at the correct speed. The good news is you can practice that on every landing.
I think the suggestion is that you can practice every landing, you don't have to succeed in the short distance, or the spot landing, just work toward it....
The sky, and the interface with the earth, don't know if you're flying for fun, or the most serious pursuit. They demand the same attention in any case!
The only landings during which I'm not practicing some skill, are those occasional ones when I have to pee, and just want to be down and clear with the least commitment....
