You are completely right here.

 

Personally, I treat position sizing as an "adjustable power dial/knob" that can both proportionally increase both the return and risk of a system when need to be. If a certain power level of a system produced a historically tested risk that is unacceptable to the user, then he/she should reduce it proportionally. If the return at this acceptable risk level is unacceptable to the user, then he/she should further improve his system by either having better entries / exits (mainly exits), or be creative in money management techniques and even with the power dial itself.

 

Systems should be compared based on their return/risk ratio. There are many definition of return and risk, so how you define it is up to you.
