I reckon everybody has a natural level that they can do then after that becomes a matter of other influences, fitness, body type, natural ability, reach, desire/care factor, style etc...so once you reach your natural ability/grade etc it becomes exponential as your having to adjust a lot more parameters to achieve higher grades...which really is just a time thing assuming your motivated enough.
But 25% sounds about right though I lean more towards 26% after rounding up :) |
