I think that the rating of La is much less important for a short-term strategy than for a long-term strategy.
To take the example of PUL, the goal of my strategies is to take only a few pips profit in a very short time.
Take profit is therefore fixed in order to obtain an optimal success rate.
The stop-loss is larger to avoid as much as possible that it is activated to wrong.
If it were shorter, the trades would then often be closed by a SL to be opened again a few minutes later, which would multiply the fees (spread + commission).
Fees represent a large part of the potential profits from my strategies, so I have to minimize them to the maximum.
If there were not this constraint, it would be quite possible to improve the rating of La.
A long-term strategy does not have this problem because the fees represent a much smaller part of each trade.
Moreover, the time scale is not the same. In my opinion, letting your losses run for a few hours is not the same as letting them run for days or even weeks.
