The first time I processed a 15 foot roll if 70mm I reversed the stop and fixer steps... However, it's been a year and the images are just fine, napery came out exposed correctly and they still look good... Makes you wonder...
The fixer would stop the developer. Without the stop bath first, the fixer does not last as long. The stop bath after accomplishes nothing and gets rinsed out with the washing. Just one of those survivable mistakes. Now if you used the fixer first followed by the developer, it would not have been so good!

I leave the digital work for the urologists and proctologists.
