To convert your timeslip ET and MPH to sea level. Multiply applicable factor times your ET or MPH.

(Example: You ran a 14.4 @ 103 MPH at 5000' elevation track. The correction factors are .9367 and 1.0661 for 5000'. (14.4 * .9367) = 13.50 , (103 * 1.0661) = 109.80 MPH. So the correct timeslip would be 13.50 @ 109.80 MPH at sea level)

FT above Sea Level | Elapsed Time | Trap Speed (MPH)

1200 .9874 1.0129
1300 .9861 1.0143

2200 .9744 1.0269
2300 .9731 1.0283
2400 .9718 1.0297
2500 .9705 1.0311
2600 .9692 1.0325
2700 .9679 1.0339
2800 .9666 1.0353

4100 .9497 1.0535
4200 .9484 1.0549
4300 .9471 1.0563
4400 .9458 1.0577
4500 .9445 1.0591
4600 .9432 1.0605
4700 .9419 1.0619
4800 .9406 1.0633

5000 .9380 1.0661
5100 .9367 1.0675
5200 .9354 1.0689
5300 .9341 1.0703
5400 .9328 1.0717
5500 .9315 1.0731

The differences are .0013 per 100ft on the time and .0026 per 100ft on the mph.
