Here is a little suggestion, to avoid competitors to know about easy scrambles (for example 2x2x2 WR).
We could have 5 scramblers, each one will do only 1 scramble, and note which one he applies on the cube (on the verso of the scoree sheet ? Or on an other sheet, so the competitor will not be able to see it, but it seems more hard to do). So, if you see that a scramble is lucky (for the 2x2x2 WR, or for my pyra NR, i admit that i saw somebody averaging around 10 doing a 3.xx, but i think i would have seen it anyway), you don't know which it is, and even if you already did it. It will be useful for people doing other methods than the more popular ones : i'm not in face-first for 2x2x2, but if i saw a 0.69, i would have searched for an easy face... Which i won't have done without this indication.
It has many pros, I listed them already. An other one is that a scrambler would know very well the scramble he has to do, and do it a bit faster than an other one.
The only cons I see is that we will need 5 scramblers for every event (but 1 scrambler can still do several scrambles), and scramblers may forgot to note the number of scrambles.
Thank you for reading, I hope that it has not been proposed yet.
