Times achieved at an altitude of 3,000 feet or more may be adjusted as provided in Section 207.11.5 of the USS Rules and Regulations for the purpose of entering higher level meets.

Below is the complete text of Section 207.11.5 from the 2005 USA Swimming Rules and Regulations. The topic of this section is the adjustment of achieved times to be used as entry times for national championship meets.

Times achieved at an altitude of 3,000 feet or more may be adjusted as follows:

Event Distance	3,000'-4,250'	4,251'-6,500'	above 6,500'
200	.50 sec	1.20 sec	1.60 sec
400 or 500	2.50 sec	5.00 sec	7.00 sec
800 free relay	2.00 sec	4.80 sec	6.40 sec
800 or 1000	5.00 sec	10.00 sec	15.00 sec
1500 or 1650	11.00 sec	23.00 sec	32.50 sec

Subtract the time indicated above from the actual time achieved at altitude. This is the time to be used on the entry form and seeding will be based on that time. Information relative to the adjustment accompanying the entry form must include name of swimmer, event, date of performance, elevation location, actual time, corrected time, and signature of coach.

A swimmer or relay may use the above adjustments to meet the national qualifying time standard and seeding will be based upon that time.
