I have 3 X/1999 cels numbered respectively A26, 
A42 and A74. After having watched the scenes of 
the movie very carefully, it doesn't seem that 
those cels were the 26th, 42th and 74th used in 
their respective shots. (Especially for the A74, 
used in a shot that doesn't even last for 10 
seconds) Is there something I don't know about 
cel numbering, am I mistaking ?
