Help with puzzle!

Hey guys, I'm doing the void stares back and can't seem to get the weight puzzle too well. I have a few different weights and have to figure out the order they actually belong in from lightest to heaviest. Math wizzes, go!

EDIT - IT'S THE SAME FOR EVERYBODY.

i don't know why the fucking guide doesn't just tell you the combination. FOR ANYBODY LOOKING - THE CODE IS 42635~~~~~~~~~~~~~~~~~

 

Security Room 1 : The Weight DistributionEdit

The crate room.
Talk to Captain Gilroy and you will automatically go through the big metal door. Behind it is a room with some crates. You will view a cutscene of a black knight dying while trying to open the door.
Search the crates and you will find there are blocks in them. You need to fit them into the door's locking mechanism, but the labels on the blocks displaying their weight are incorrect. Captain Gilroy will tell you that he can determine the blocks' actual weight.
Take all the blocks out of the crate. They are numbered from 2 to 6. Now use two on Captain Gilroy at a time. He will tell which one is lighter and which one is heavier. You have to find out the correct order of blocks, from lightest to heaviest. Keep using pairs of blocks on Gilroy until you know the order. Arrange them in your inventory from lightest to heaviest.
When you know the order, talk to Gilroy and choose the option "I think I've got it." Now give the weights for each block, starting with the lightest one and so working your way up to the heaviest one. For example, if you found the order of blocks is 3, 5, 2, 6, 4, start with block 3 (which weighs 2), then tell the weight of block 5 (which is 3), and so on. (Label 2 is 4, Label 3 is 2, Label 4 is 6, Label 5 is 3 and Label 6 is 5)
After you've told Gilroy the right order, he will tell you to correct the scales on the door. Today's password is "15". Blocks must be arranged such that the weight on each bar adds up to 15, and such that the leverage of the weights on each side of the swivel point is equal. The weight labels are correct at this point. Solutions for the top bar are 3-4-6-2, 3-5-3-4, 4-4-2-5, or the reverse of any of those. The solution for the bottom bar is 2-2-5-6.

A possible solution.
Notes:
Remember block 2 does not have a weight value of 2; the number 2 is simply its label. This of course applies to the other blocks as well.
The lighter a block is, the lower its true weight value will be. The block that weighs 2 is the lightest one, the block that weighs 6 is the heaviest.
This puzzle is different for each player.
The easiest tactic is to first find the block that is lighter than all others. Put it apart, and find the lightest block of the remaining ones. Put that one apart too next to the first one, and repeat these steps. You'll end up with the correct order.
