the ncaa app is of course gold standard but it appears to only assess hypoxia on metabolism & doesn't appear to me to incorporate reduced wind resistance/gravity
to do this, modify the ncaa app times with wind altitude calculator :

- 1'43.86 at nairobi at 1661m ( 5450' )
nearest venue just below this on app is denver at 5276' -> 1'43.21
then adjust with 2nd calculator which is converting 1'43.86 to 100m = 12.983s & input into it with 0 wind & 1661m -> 13.05
-> final corrected time is 1'43.21 * ( 13.05/12.983 ) =
1'43.74
which means nairobi is slower than sea-level for 800m by about 1/10 s which no one woud notice
it is much different situation if you do the calculation for mexico at ~ 7400'
- 3'30.89 using denver as proxy -> 3'25.84
then adjust with 2nd calculator which is converting 3'30.89 to 100m = 14.06s & input into it with 0 wind & 1661m -> 14.133
-> final corrected time is 3'25.84 * ( 14.133/14.06 ) =
3'26.90
as denver is lower than nairobi, then that works at at about 3'26.6/3'26.7 if nairobi was in app
that was with pacing to only 700m according to canova & wouda been ~ 3'26-flat with drafting to bell
not bad going considering prelim in their legs
in a serious paced run at sea-level Ronnie can definitely dip into 3'25s & Timmy just behind
this just "confirms" what i have been saying for recent weeks : Ronnie & now Timmy are both in shape to break 1500wr
i suggest you look at the all-time lists
Asbel/Silas have run plenty of times in nairobi & best they have run is 3'32.2/3'31.3 & have gone 3'26/3'27 at sea-level
that "not much faster at sea-level" ???
