THE THREE
PERIODS IN CHRONO HISTORY
|
A)
Until 1968
Only hand timing is official.
B)
From 1972
Also electric timing is official. A second world
list is created for "electric" records in all
running events up to 400 metres.
C)
From 1977
Only electric timing is official. Hand timed lists
are no longer updated.
Particular
features of 1968-1971 period
The new electric lists open with the best result ante-1972.
The best mark in Men's 100 metres is 9.95 by
Mexico City's (1968) Olympic winner Jim Hines.
Electric timing was semi-official and 9.95 is only
the reconversion of the official 9.9. It's
interesting to point out that this mark was
already registrated as a world record in hand
timed official list. So it appears twice! What
happens from 1972 on? No hand timed record is
anylonger reconverted.
Particular
features of the period 1972-1976
Both lists are official, for it happens that in
the same event two athletes are both world record
holders, the first in hand list and the second in
electric list (men's 100 metres: Steve Williams
and Jim Hines). Furthermore, some athletes,
especially between 1973 and 1975, ran only hand
timed races; just for that they didn't break any
electric record.

WHO SCORED MORE RECORDS
BY AGE?
This is the last part of my
research. After writing records chronology, I counted
records made by every athletes and ranked athletes with
more records by age.
I took into account all
athletes active in 1976 and following years. So, for
example, Willie Davenport (active 1963-1978) is there,
Ralph Boston (active 1959-1972) is not there.
I had some problems with
speed races (100-200 metres and 110 hurdles). There's a
real case which explains them all: Poland's Irena
Szewinska (1964-1980).
Her records strip on 100
metres with electric timing is as follows:
8
|
Irena Szewinska
|
1946-
|
22 26 27 28 29 30
31 32 33
|
Capture: 8 is the number of
records she broke in her career; after her name and her
birth year I wrote the ages of her 8 records.
In 1972 Irena was 26 years old. What about her before? We
have to look at her hand timed performances:

(I didn't count her beaten
records because after 1976 hand timed lists were no longer
updated)
Let's put them together and
have a look:

Something matches and
something doesn't.
Matching ages: 22, 27, 28
and 30 years. Szewinska was the first both in hand and in
electric list.
Not matching ages:
- Records at 19 and 21 years of age, scored when
electric chrono wasn't official. So Szewinska could
not score any electric records at that age.This
means Szewinska holds two more records by age: 19 years
(1965) and 21 years (1967);
- Records at more than 30 years of age, that is scored
after 1976, when hand timing was set apart for
good in official races. It's simple up to this point, I
suppose. Here comes the hardest part:
- Records at 26 (1972) and 29 years (1975). What has
happened? Szewinska scored a new record only in electric
list.
Irena Szewinska did 11.33
in 1972 at 26, thus setting a new age record. But at the
same age, in 1970 Chi Cheng (Taiwan, 1944) ran 11.0 hand
timed. What am I to do? Who's the age record owner? I
thought to apply IAAF rule which says that, to compare
hand timing and electric timing on 100 metres, 0.24
seconds have to be added to hand timing. Adding 0.24 to
11.0 I have 11.24, which is still better than Szewinska's
11.33. Thus I take off the record to Szewinska and
assigned it to Chi Cheng (the Taiwanese held this record
until 1976, when Annegret Richter of FRG did 11.01 and
10.8).
I applied the same rule on 1975 record: Szewinska did
11.23 at 29 (new record by age). Three years before Eva
Gleskova for Tchekoslovakia did 11.0 hand timed. After
IAAF rule the record, this time, was Szewinska's.
Now, let's have a look
again about Szewinska's records strips:

"26" is red to show that
it's not a record by age.
Now I can number all
Szewinska's records on 100 metres. They are 10. As you can
see from the first left column (6 and 8) neither electric
table nor hand table, alone, are enough: number 10 emerges
only from their comparison.
Greg Foster vs. Rodney
Milburn
I said Irena Szewinska's
story explains all problems I met during my research about
the period 1972-1976. It's not just like that. A last case
happened to hurdler Greg Foster, who ran 13.28 in 1979,
setting the age record at 21 (he bettered a 13.42 of
1968). I forgot on the contrary that before, in
1971, Rodney Milburn marked 13.0, so Foster didn't improve
Milburn's record. I didn't think about one fact: a post-1977
record can be cancelled by a hand timed record ante-1977,
also if from 1977 hand chrono is no longer official.
To come to an end, here's
an award to those who managed to follow me to this point:
the list of all cases similar to Szewinska vs. Chi Cheng
and Szewinska vs. Gleskova. Have fun and decide whom the
record has to be awarded to! Issues
