Veteran and Expert are not WGT Tier names. All the coin rooms allow ANY player, regardless of their tier to play. Limiting which tiers can play in each room would be unfair as not everyone wants to risk the same amount of coins. I believe the rooms try to match up players as close to even in skill as it can but sometimes lower level players will get matched up with higher level players. The three lowest coin rooms have a bit of a handicap to compensate for this built in as the tees are set to a players tier. The higher the tier a player is the further back they have to tee off from. This helps to level out the skill gap a bit but is not going to totally eliminate the advantage.
The names given to the Showdown’s have NOTHING to do with which players are allowed to play in each level. Any player all the way up to Tour Champions can play in any of the three Showdown levels. The only real difference between the three levels is the amount of credits that you have to pay as entry fees (10, 100 and 1000)
IMHO the individual Showdowns rooms should be separated by Tiers similar to how WGT tournaments are so that participants only play against similarly skilled players.
Putting Champions and Tour Champions in the same showdown groups with lower tiered players in the 10 and even 100 credits showdowns effectively makes it nearly impossible for the lower tier guys to compete.
And I’m not saying that it’s the Champ and TCs fault either as they should not be expected to only pay 1000 credits to enter. I totally understand that not everyone, regardless of skill wants or even are able to wager that much
