Hi mpmartin, yes this is consistent with previous years. USMS has a lenient refund policy (compared to other types of sports/events). Swimmers can request a refund for any reason up until a week after entries close: April 3 entry deadline, April 10 refund deadline.
I was entered to Nationals and then withdrew when a family obligation came up. 20 people withdrawing from a 2500 person meet is less than 1%. It is not surprising that a few people had stuff come up.
