Look at it mathematically. 6619 total entries. I think the maximum number an individual could earn was 47.
47/6619 = 0.007 * 100 = 0.7% chance
Those are thin odds for even the highest ticket holders. So, even if you had 6 entries (a minimal effort to say the least) your 0.1% chance of winning isn't TOO far off from the highest holder.
In short... it's really anyone's game!
Lol I had done the math right from the beginning, but I'm glad that you posted that to give everyone a bit of hope!
