What happens do my other placements if I dodge a lobby with a different role

So just out of curiosity what happens if I dodge a lobby on say top. Do I lose 1 game for ALL placements or do I just lose 1 game for my top lane role? Also is there a way to see how many games you're into your placements besides post lobby?

Edit: I dont know if it counted as a lose but i lost 3 lp in my other roles. I don't get why dodging makes you splash -3 to all roles. That seems a bit much. You kind of need to make use of dodging at times for troll teams but now if you dodge a lobby you lose -3 lp and only gain +3/+6 splash when you win. I get dodging too much is a problem but that was my first dodge, I think that should be addressed to maybe -1 or dodging should only effect the role you're on. If you win the next game you only break even and if you lose you just got -6 in all roles.
