Regardless of aspect ratio, at some point your speed selection is limited 
because the patch gets too small.  That's why with Meta-Speed, for example,
you can't select most speeds between 30 and 40 fps on a MKIII.  The inverted 
scan with the flip allows the Gold more usable sizes and speeds, and it is 
useful for Super-16.  There is a feature in development for the 
Quattroscan in conjunction with Meta-Speed which will give you 
continuously variable speed.  IE, you could dial in a speed, the 
machine would just do it, and the patch would be ok.  This will remedy 
limitations imposed by the present method of counting vertical intervals 
to determine valid speeds.
