That's basically it.
A lot depends upon the system you use and the exptancy it produces coupled with the frequency you trade and the % of trades you expect to be profitable.
daytrading 200 scalp trades per day with a 75% success rate will probably show less variance over time than trend following with a 33% success rate and making a dozen or so round-trips per year.
Both systems can have the same expectancy for each unit risked, as the longer-term system can sometimes return huges multiples of the initial risk, although it will probably show more variance.
