Ed,

For me the positioning of each figure in this year's Advanced is the main advantage of tons of practise.

In the case of #1 (hammer) and #2 (roller) - I enter, go a bit beyond the centre, and then do the roller back through the centre (as in the end point in the first 90 degrees is about centre box, and the end of the last 90 is there too (right in front)..

In the case of the pushout to top in the next figure - I position that for the downline snap that comes up in two figures later.. (nothing worse than being too low when facing a 3/4 roll AND a 3/4 snap!)

It all gets a bit confused for me when I practise the 'other way' - I don't have a caller, so memory sometimes 'fails' me a bit when practising from my 'non natural' side..

Cheers,
Bob
