There is some truth to this, though the ladies are in the dark about whether their exercises are done correctly and whether they're on the right track. Having a device to quantify their efforts and progress might be valuable to this group of people, especially in cases of initially unresponsive PF's.

You don't need to spend money on a lot of things in life but your time is limited, this is where a trade off becomes necessary.

Just as there are people who can afford to hire a personal trainer to quantify and monitor form and progress without their own independent research, there are people who can afford Pericoach to observe key signatures of form and strength improvements.
It's obvious that Analytica and its shareholders are hoping there are enough women interested who have this medical condition and can afford Pericoach.
