So I recently learned how to be color neutral for big cubes and one common problem that when doing the green cross, I only know the cross edge order for white, orange, and red, but not red and yellow, and for red cross I know the order for blue, white, and green but not yellow and blue. So, when doing 5x5 at home I will have a 3x3 close by and put it in the red on top yellow on front orientation, so depending on what centers I decide to do I can look at my 3x3 during inspection to see which order the cross edges will be in for the cases that I don't know. Is this legal to do officially?
tl;dr: Is it legal to use a 3x3 to memorize color orientation officially during a big cube round as long as I don't touch the puzzle?
