I am sorry I'm not sure what you mean.
If you trade with less market exposure than the average of your 3 last months, this is what we are measuring on Activity. And the result is less Activity for this month.
If having less market exposure leads to greater results, this is what we are measuring on Monthly Return.
We can not measure two times the same thing (returns).
Please, take into account the DarwinIA ranking is based on three aspects: Activity, Returns, D-Score.
Also, if you are having a different approach to the markets and trading less, the next month you will obtain 100% Activity sooner.
Let me know if I am not clear.
