Maybe as you revamp the badges, add one, two and three star to each
of the higher badges (like you do with Gold Star Master) and then
space them 20,000 points apart. If you did that, you could
have Platinum Star Master (PSM) at 120K, PSM * at 140K, PSM ** at
160K, PSM *** at 180K, and then Black Star Master (BCM) at 200K.
Then Green Star Hero would appear at 280K, Blue Star Hero at
360K, and so on. You could also add additional colors like
white, yellow, orange, and at the top, have bronze, silver, gold,
titanium, palladium, platinum, quartz, ruby, and diamond.
Then if that is not enough, add say "Grand Master" badge
hierarchy. It will be interesting to see what you all do.
