Is my GFs treatment justified? Or are we getting ripped off?

Hello, my girlfriend had a special kind of therapy using tapes. Pictures and drawings are made by the doc. This is about 10 weeks into the therapy. On the first glance it seems, she’s making good progress. But I feel like in the first picture, the doc didn’t make the lines properly so the angle is measured greater than it actually is. In the second it seems to be drawn and measured more reasonably. Is he tricking us into thinking the therapy helps more then it really does? Thanks for your input
