Tennant is certainly adapting to his view, in a more modern style.
If it is not for a piece of music application, I wouldn't care practicing only the best fingering to develop a pattern, or group reflex. I would rather do the opposite: try the different fingers, the easiers and the more difficult ones, work them to free up your tensions, acquire better hand/wrist/arm positioning, check economy of movements etc. Every time you group blocks of patterns you are working on reflexes memorization, rather than on technique improvement. Use reflex memorization if you will apply and use it in a specific piece of music you are working, avoid pattern and block reflexes if you want to work on technique improvement.
