Day-master strength is a ratio; when what feeds you is overwhelming and the season is entirely on your side, that's very strong. The tradition has a particular handling for this chart called 'following the strength': almost nothing on the chart can control you, so stop trying — ride the force to its end. It mirrors 'following the current' for very weak: at both extremes the talk stops being about balance and becomes about spending the force fully.
The mechanism is this: you're not short of fuel; you're short of things big enough to burn it. On small matters a very strong person reads as too heavy, too fast, too much — not because you're wrong, but because the thing can't hold you.
Where you'll recognise it: hard to persuade, hard to move, almost never tired, people around you struggling to keep up. Running well, you're the person with the greatest carrying capacity: you bear what others can't, finish what others can't, and hold steadiest in the largest arenas. Stuck, you can't bend — not hearing, not yielding, flattening the people around you. So the most important lesson for this chart isn't getting stronger (that's done); it's learning when not to press. And that lesson is usually taught by something genuinely large enough.
