What do we really want, i.e. what is the spirit of the 200m rule? I
think it is to measure the maximum speed that can be achieved with human
power in any self-chosen time (any runup) and maintained for a short
time (200m, but could be less). The accumulation of kinetic energy
I agree.
would nevertheless propose a tolerance of 1.5m in order to be able to
use the lower part of raised banked curves. Also, this is easily checked
by sight, as 1.5m is a typical height of observers' eyes.
I've talked with Hans van Vugt about the 200m sprint rules. According
to him the 2/3% limput currently used is already quite scrict an there
are few track (even in a flat country as The Netherlands) that adhere
to this rule.
Also according to Hans, the hight difference at Dreka is more than 2
meters, making it an invalid track when using Theo's proposed rule.
According to me there are two Issues:
1) Defining what our margins for flat are (Can be the difference
between the highest and lowest point cannot exceed X meters and/or the
slope cannot be more than Y degrees.
2) How accurate must those measurements be. Both in distance do we
measure every meter, every 100 meters or just at the beginning and the
start and how accurate is the height measurement. Do we require cm's
or meters or something else.
Although I applaud the errorts of HPV Germany and Heike to organise
record races at the Dreka track, I don't want to be our rules based on
just what's possible there. To make it possible to have record races
all over the world I'd like to ask our members the following:
Please select a track that you think would be good for 200 meter
flying start races. Determine how accurate you can get the hight
profile of it and record that high profile.
I would want to legislate the 200m flying start in such a way that the
majority or our members will be able to hold record races. So we as
committee should not set arbitrary rules, but investigate what can be
reasonable asked from our members.
199m (allowing comparision but not confusion with the old records).
We could set it to 200 yards, which leads to American records in
metric and rest of the world in imperial.
