I don't doubt you.
There may be a reason why our experiences differ so much: There are a lot of better playing opportunities here for strong 4.0 guys.
In DC Metro, many people play in VA, MD and DC at the same time. If a high 4.0 guy wants to join a team, he can have three teams just by playing 8.0 mixed (in addition to his three play opportunities in men's combo 8.5). Who has the time or interest to take on a seventh team by playing Xtreme Keepaway in 7.0 mixed.
