Hi Woodwzrd,
It's my understanding they will give you scores at the Mid western, but I never entered any calls there so I can't say for sure. I know it's not common practice at the Nationals but after a computer glich last year moved my call entery to second place I questioned it. My scores where written down and brought to me and the gentleman explaned the scoring and where the call was weak. The difference of 1 point seperated 1st and 2nd.
It was helpful to know where I needed to improve. I changed my finish to a gloss this year and placed 2 of 3 calls
1st. Read over the judging process on entry forms and know where the highest part of scores come from and concentrate on those things first. Hope this helps.
