The book says
Take up one exercise or form at a time and stick to it until you have mastered it, or at least made substantial improvements. As a rule, two or three pages at least should be devoted to a form before going ahead. Not infrequently it is necessary to cover several sheets with a form before improvement is shown. Improvement is more the result of critical observation and careful effect than prolonged but indiscriminate practice.
One page is all I could muster tonight. A few more pages over the weekend for sure.
