In order to gain progress towards the gladiator title, you have to have a streak of consecutive wins, 2 or more. Winning one match and losing the next doesn't gain any gladiator points. Getting a streak of 5 victories, then coming back another day and winning once doesn't do anything. Anytime you try RA, you have to win at least 2 matches in a row to gain gladiator points.
I hope this cleared things up? =)
