What's great about many women is they don't have preconceived notions about how to shoot. Therefore, they listen and do what they are instructed to do, as opposed to the typical guy, who thinks he already knows it all and fights instruction. Women often are shooting very well early on in the game as a result.
In other words, it's all in the instruction, so you must be doing something right.
Of course, you know she'll shortly be picking out her own guns and such.
