Ill give my 2 cents.
Perfect example - today we did a 'mock' test before next weeks real test.
A guy a bit bigger/stronger than me resisted, pretty much full on, throughout the whole technique and with all the techniques. (It was literally like moving a log.)
Funny thing is they were instructed NOT to do this during the (mock) test.
Who knows, guess we all have our bad days...did the moves regardelss.
But it got me to thinking that a little atemi here, and if we could have switched techniques would have put a new perspective on things for uke.
Again, all things happen for a reason - perhaps its a reality check for me not to get to comfortable in movements thinking Im doing something and then get surprised if there is resistance.
