Long term OG records

[catson52]

Most OG records are relatively recent. Some date back to the eighties, and one (by Beamon) will now make it to 43+ years. I note that the other great Mexico City record (4 x 400 m) has only been lowered marginally.
So altitude and wind assistance gave us a LJ OG record that stood up for over forty years, yet the TJ from 1968 (17.39 m if I recall) has been exceeded quite often and by many performers. The WR is over 80 cm further in the TJ, and only 5 cm (and that on a single jump) in the LJ than Beamon's monster. Does this show the greatness of TF's most famous moment or point to Johnathon Edwards' greatness?

I think it might indicate that the earlier TJers were relativley weak. It is a much more technical event than the long jump, and more difficult to master. Sure, Beamon did something fantastic, and Edwards provided some repeated forays at or near the WR level. I just think that the TJ was a bit softer, recordwise, than the LJ.

Just my two cents.

[imaginative]

Two very simple considerations shows that 8.90 was much stronger than 17.39:

1. Only one wind-legal and official mark has ever exceeded 8.90; 17.39 is a
joint 422 on Pela's list.

2. Saneyev broke the WR by 12 cm, resp. 36 cm compared to pre-Mexico; Beamon
upped the WR by 55 cm. Proportionally speaking the difference increases by
roughly a factor two.

(Whether the general level of triple jump was lower than long jump is not
clear from the above (a much deeper analysis would be necessary); however, it
does seem likely.)

not strictly related, but an estimate of wind/altitude corrections in tj compress the tj all-time list & puts je's wr into perspective

this is list of greatest jumps in hx

18.43 +2.4 Jonathan Edwards GBR 10.05.66 1 Villeneuve d'Ascq 25.06.1995
18.29 +1.3 Jonathan Edwards GBR 10.05.66 1 Göteborg 07.08.1995
18.17 +2.1 Mike Conley USA 05.10.62 1 Barcelona 03.08.1992
18.09 -0.4 Kenny Harrison USA 13.02.65 1 Atlanta 27.07.1996
17.89A ±0.0 João Carlos de Oliveira BRA 28.05.54 1 Ciudad de México 15.10.1975
17.83 Aliecer Urrutia CUB 22.09.74 1 Sindelfingen 01.03.1997
17.83 Christian Olsson SWE 25.01.80 1 Budapest 07.03.2004

now, all jumps are assumed right on the board ( unless someone can provide data on how far behind they were ? )

& using jrm's calc

http://myweb.lmu.edu/jmureika/track/wind/index.html

use 50m & 60m calc & assume they all had ~ 10.4 speed which translates to ~ 6.70 speed for 60m & ~ 5.78s speed for 50m ( you can use most any times from 6.40/5.57 to 6.90/5.94, it changes the calculations by virtually nil - consistent numbers are what counts )

we'll use 6.70/5.78 with difference of 0.92

input those times for all of above, find corrected times & divide into 0.92 ( use 3 decimal points part of calc )

this gives correction, which has to be squared as wind/altitude assists/opposes both in run-up & in the 3-jump phase

anyhows, using that, corrected "basic" list is

18.09 -> ~ 18.12

18.29 -> ~ 18.05

18.43 -> ~ 18.03

18.17 -> ~ 17.85

17.89 -> ~ 17.65

intrinsically, i'd suggest kenny's jump is best basic jump of all-time ( assuming all spot on the board )

it also indicates idowu who has had toe-sand jumps of 17.83 woud be at same level with je if he coud lose that crappy legshoot

go look at kenny's jump again - possibly greatest jump in history

jao's jump, indicates wind is more important than altitude
