Thanks for your inputs! I think I have made my picture a bit wider after this thread and as far as I understand we ought to have more x-wind practise to train up the thecnique and coordination.
I think the reasoning between student and instructor is a good way to find out if the prevailing conditions are within the student's capacity. However, I think after all the dual training we've had we should be able to practise it on our own and not cancel due to 6-7 kts. crosswind. Not that I have to do all my x-wind practise solo, but it is another feeling when you know you have accomplished something totally by your own.
