We're organizing a trip to Moscow by railcar, so please leave your phone numbers here so we can stay in touch. You want to bring a trailer? Sure, we can bring a trailer:D
Regarding the main topic: Many people can add a few more pull-ups if they try, so you shouldn't have written how many you can do right away. Someone will probably add 2-3 pull-ups to their total;). If you want, I can help with the contest, even though I'm participating myself:). In general, don't give up on the contest; it's a great and interesting idea.

Well, you amaze me... I did 20-25 push-ups every day in school, and my record was exactly 50, but that was at some kind of sports event, and I took first place.
But I'm not a MAN!

Uh... there seems to be a mistake here. We're talking about pull-ups (reaching the bar so that your chin is above the bar;), and preferably without jerking, so that it's all done cleanly, because if you jerk, I can do 50:)), and not push-ups (from the floor with your hands), and they should also be done cleanly (without bending your back, and when lifting from the floor, don't arch from the hips to the deltoid muscles, because that helps a lot, I'm not kidding (if you're going to do it, do it right:))).
