You get 50 Rep for a win. Medallions give 40 rep, up to 200. The shader, emblem, and class armor each give a (multiplicative) 10% rep boost, up to 33%. Tempering gives up to +150% rep boost on the last day. Add all this up, and you can get up to 500 rep for a win on the last day, and 100 rep without the medallions.

50 points for victory 40 points for medallion 10% bonus for each emblem, shader, iron banner fraction fashion wear then buffs 5, 12.5, 25, 40, 60, 100, 140 If you are not going to play one day but can the next day get your bounties before the reset then you can do them twice the next day edit: I was wrong about the bounties as I could see them the next day when I redeemed them they disappeared

when does the iron banner end?

Today, Thursday, with the Tempered Buff and all 3 items (Class, Emblem, Shader), the following were the values I recorded: 82 points per win 67 points per medallion redeemed 166 points per bounty completed

It's arbitary for the most part. 15-25 IB Rep Points for a win, zero IB Rep for a loss. One medallion is a little under the Rep gain from a win. Each aesthetic item(cape, mark, bond, shader, emblem) adds 5-10% per item. And the Tempered buff varies day to day, but constantly increases in Rep bonuses.
