what is re-born firenze now for lanes ???
what is re-born oslo now for lanes ???
6-lanes is mickey-mouse
wrong
no auto-timing
1/1/81
wrong
utter rubbish
it was from photo-cell which is not accepted for wr even in '81
there was no auto-timing for coe's 800 !!!
his firenze clocking was nonsense
no auto timing & mickey-mouse 6-lane track
no one woud accept a 6-lane tracking clocking today, as tracks shoud be
116/84 & 8 lanes
no way anyone shoud accept that mickey-mouse 6 lane track in '81
There have been many world records set on 6 lane tracks, and there is nothing in any document published by the IAAF that states times on 6 lane tracks are not acceptable.
"Running tracks can have a variable number of lanes (typically from four to nine) and, in accordance with IAFF requirements (International Association of Athletics Federations), each lane is 1.22m wide."
Number of lanes are irrelevant and a total red herring. The only prerequisite is that it is a 400m track and the lanes are 1.22m wide.
Likewise, no IAAF rules state that tracks have to have 'standard' 84m long straights and 116m curves for record purposes.
Moreover, scientific testing on tracks with longer straights and thus tighter bends, is actually a disadvantage to athletes and slows them down.
Even if the old Oslo track was of a different configuration to the current "standard" IAAF ones, that does not make them illegal nor faster. There were many tracks of different configurations being used in the last century, and any records set on them that were ratified by the IAAF made them legal.
"Although the IAAF standard track is the norm for track dimensions, the IAAF accepts other tracks. One type of track is the equal quadrant track, which is a 400 meter track with 100 meter bends and 100 meters along each straightaway, measured along lane 1."
“We choose the equal quadrant track (to test) because before the IAAF standard track became so popular, the equal quadrant track was preferred. However, today THE STANDARD TRACK is by far the most widely used design for a number of reasons, including A WIDER TURNING RADIUS that favors runners and ENHANCES PERFORMANCES, ….â€
When comparing times for equal quadrant and standard tracks in windless conditions over 400m, “The final TIME in the EQUAL QUADRANT track is 0.06 seconds SLOWER than the IAAF standard track simulation, due to the SMALLER RADII on the bends. This causes the runners to spend more time on the ground than in the air, which increases their time. An equal quadrant track has longer straights than the IAAF standard track, which gives the runners on an equal quadrant track an advantage to be able to run faster on the straights. However, THIS DOES NOT OUTWEIGH THE DISADVANTAGE THAT THEY HAVE ON THE BENDS.â€

So that would assume that Coe's run on the tighter bends of Oslo would make his 800m performance at least 0.12 secs faster on a current standard configuration athletics track. And that isn't taking into consideration the improvements in surfaces since the 1970's.
So you are totally wrong in claiming it made times faster. It would have been the exact opposite, if indeed it even did have longer straights and shorter bends than the 'current standard' configuration.
As for the timing in Firenze, there was an article in AW (26.1.1985)which stated categorically that the IAAF were perfectly justified in ratifying Coe's run in Firenze. It was written by Bob Sparks, President of the Association of Track and Field Statisticians, member of the IAAF Press Commission and renowned for unearthing and correcting thousands of fully-automatic photo-finish times, chronicling every sub-four-minute miler, and who played a key role in the input to the formulation and adjustment of the IAAF Scoring Tables of Combined Events.
He wrote, "The IAAF delegates responsible for the approval knew that the time was not obtained from the conventional photo - finish camera, but they considered that the system used was equally efficient in producing a time to the required standards of accuracy."
"The facts are as follows: -
1) The photo-finish film was fogged and unreadable, as a result of accidental mixture of developer and fixer in the development chamber of the camera.
2) Independent AUTOMATIC times were obtained from two digicron timing devices. The timing system in the digicron unit is activated by the starting gun, as with the photo-finish camera. Times are registered when a photo-electronic circuit at the finish line is broken; the times are displayed on a linked printer (rather than electric scoreboard) thus producing a PERMANENT RECORD.
3) There were 2 digicron units. The photo electric circuits were installed in parallel (one for each unit) at heights of 119cm and 127cm.
4) The times recorded were 1:41.727 and 1:41.724 respectively ( only 0.003 difference). The official winning time was announced as 1:41.72, but the IAAF subsequently corrected this to 1:41.73. (as the average of the 2 times would be 1:41.7255)."
5) The time recorded by the official back up timekeepers was 1:41.6.
Whatever way you look at it, he certainly broke 1:42.0 in Florence on a ratified track with automatic timing that was activated by the starter's gun and registered by 2 photo-electric circuits at the finish.
