each step must reduce the number of possible states.
Sorry, I forgot about this. You are correct that no method with this definition of step can exceed 43,252,... steps. I also didn't realize you considered most steps to be worst. If this is the case, your method is the worst possible method, along with countless others. The point of my method was that it had a higher movecount, and fewer steps are skipped. Of course, movecount isn't an ideal way to measure how good or bad a method is either. The problem is that the worst method depends entirely on how worst is defined. So your method is not necessarily the worst, but it does have the highest number of steps. My method is also not necessarily the worst, but has a very high average number of moves.
The problem with trying to determine the worst method, or worst anything, is that what the worst is depends entirely on how a good thing is defined. For some, it's straightforward. For example, if you're in a competition with 99 other people, the worst result you can get is last place, because a good result is defined as closer to first place. For the worst method, this is a lot more difficult.
I Think this post should be renamed to the “worst human viable method”
I think this could be a good idea, but it still has two issues. One is that, again, a worst method is hard to define. I think the best way to do it would be for someone to use the method and see what time they get, but some methods might be very hard to learn or get good at, and the time would depend on the solvers skill. The other issue is that it's hard to determine what human viable means. For example, is 1lll a human viable method for the last layer? For most people, no, but it is possible. And what about a method like what's used in FMC? It's not exactly viable for speedsolving, but it's a viable way to solve the cube, and if we want bad times, one way to achieve that would be stretching the limits of what is humanly possible, which is effectively what is done in FMC.
The worst method is entirely dependent on what defines worst. I propose that instead of trying to find one thing that can be measured to determine how good a method is, people can just make a method that is bad in some aspect that they think is important. We don't necessarily need an objective measurement to come up with methods that are very bad. If we try to find the objective worst method, we'll spend as much time arguing about what counts as worst than making methods. So instead, we can just make bad methods and be happy.
