Replying to DIN setting

Just got back from the shop(mounted my bindings) and not really sure if they set my DIN correctly, as toe and heel on both are at 5. I weigh 150lbs, 5 foot 7, 28.5 boot, 20 years old, type 2 but getting closer to type 3 skier. My bindings are Rossi axial3's, and range from 3.5-12. I've heard a lot of people tend to have different din settings from toe to heel as well. I went to dinsetting.com and it recomended me at 7. So is the shop wrong or the website? Thanks in advance for the help
