No offence, but many people, including myself, have got this achievement thanks to these patterns. Use them, don't use them, whatever, it's nothing to do with me, but the idea of these patterns is that it's the most effective way I found of gathering the ghosts consistently. If you found it easier to wing it every attempt, then that's great, but I was getting frustrated with that approach so tried to develop a method that yielded the same reactions from the ghosts as frequently as possible. As stated before, once you've got the pellet, it's up to you to get all the ghosts, the patterns don't help you conquer that part of the achievement because the ghosts randomly scatter. The patterns are there to help get the ghosts following you.
On another note, I'm glad you've been able to get the achievement. It's a killer and whether you use mine and FieldEffect's method or not, anyone who has this has a lot of patience and determination.
