I think you're misunderstanding what these scrambles are. These scrambles from the two-phase algorithm are completely legitimate and you in fact better to use than 25 random turns.
also, this is the same algorithm that is used to generate official scrambles, so if you really want to see how fast you are, it makes sense to use this.
