Wrong is when more targets are missed then hit. I've been doing it from handle break for so long, I don't remember what book I got it from. And my targets have been reached a very large precentage of the time. Like 90% spot on correct, when breakout occurs before 38% FIBS.
If I have to say your website is wrong, OK, it's wrong! IMO
Try it your way. If it works, more then fails, repeat it and let me know. Be happy to adjust my style for a better way.
Your way would give larger gains expect and that would be nice. But to my experience, handle breakout to target, hits within 5% of target, most every time. And I'm happy with that result.
