It would be great if there was some graphic or so where a user could determine how many credits would be needed to reach a certain position
for each project and BOINC total!

Every 5,000th position for bigger projects, and 500th for the smaller ones
would be fine!

And maybe the changes since yesterday, one week ago,...

That's one of the things i look up most, and i need to load it all by hand, so i think this would significantly decrease server traffic, too.
(If others do so, too, and not only me... !!!)
