Can i get some xp for slamming my reroll button for 40 minutes.

With the change a couple days ago, if you're going for rank 3s you pretty much HAVE to be rolling early. Something you can only do if you got good item RNG you can go for a winstreak. If you got bad items and you have to tank your HP to build econ, don't even go for rank 3s. Think of it more like a blessing, in that situation, than an eventual upgrade.
