Tessa, I'm 100% sure all of the entries were in to win - but of those, realistically you could cut that by 2/3 that they knew they were in for a serious chance. heck, if I could've entered, I00% I would have been in for the ultimate dosh prize but would have known my chances were remote.
My point re learning and growing was many mediumites get snippy at editors for either not accepting their work as is or baulking at suggestions to improve on REGULAR submissions. Take heed of their ideas because when it comes to a contest, you are on your own. ( and I'm not talking about you!)
