I have came up with the perfect Cobblestone strat to win you a round
First you have to know that they are going to push you. Now you have someone listening waiting for them to hear them push then we he calls out there pushing player 2 throws a decoy right outside of the portapotties. Then player 2 and 3 both smoke each portapotie exactly 2.67938 seconds after the decoy is thrown. Now player 2 hides in the second porta potie and player 3 hides to the side of the second one being covered by the smoke. Player one who is listening now jumps on top of the head of player 2 and he will resmoke it by at 14.61 seconds after the first smokes are thrown he will aim his crosshair 14.6 degrees up from level and 8.85 degrees east while looking south and then underhand it. Now at 3.44 seconds apart player 2 and 3 should flash into the smoke because it is virtually unseeable. Now player 4 will be in tower watching backside who will then pick someone who pushes from that side and then when there is 7.1 seconds left on the second smoke he will jump out of tower from window and 444.6 degree turn counter clockwise and mid air throw smoke to portapotie. If this is perfectly timed it will smoke just as the second smoke is leaving. Now 2 players from the porta pottie side will push and shoot first porta potie but know one is there. Player 5 who will still be right above spawn with an awp will pick the first guy then running back without getting picked and rotate over to tower. Player 4 will be at spawn now. Now 1 more will be there and get killed by the two guys ontop of each others head. Right after getting that kill they will full out crouch walk all the way towards spawn. Then as they are getting gunned down from the third rotater The guy in porta potie will jump out and kill him. Now player 5 who is in tower will do the 444.6 degree spin counter clockwise out of tower smoke to give player 2 a chance to escape. Now it will be a 3 v 1 as your team is rotating over to a to take site.
