What happens if we have a twenty minute time interval between
start clock opening times?

Case 1b.

The first pilot gets 1000 points, as before. The second pilot flies just as fast
getting the same distance and speed points, but loses 68 of the possible 112
leading points and 54 of the arrival position points receiving a total of 879
points compared to the earlier comparable case of 904 points when leaving on the
second interval ten minutes behind. The doubling of the time interval didn't
make for a great difference in the points allocation.

Our second case where the time interval would affect the outcome:

Case 4b.

Here again, the leading points are the same for both pilots (and instead of
being full leading points are given to both pilots). The difference
between them is speed and arrival position points. Our first pilot is slow and
while he starts out in front is passed at the half way point and comes in twenty
minutes behind the faster second pilot. The second pilot receives 1000 points,
while the first pilot receives only 649 losing 298 points of the 447 speed
points available and 54 of the 80 arrival position points. Compared to our
earlier case of a ten minute interval the first pilot went a lot slower and
therefore lost quite a few speed points.

Perhaps the first pilot noting he would be slower headed out first hoping to
claim leading points, and he got them, but so did the faster pilot starting out
behind him. The first pilot was fooled once again by the name for the 'leading'
points.

Our third case:

Case 6.

The first pilot wasn't that slow (same speed as he was in our first case above)
and he stayed in the lead until the tie at the end. The second pilot gets 958
points losing 42 of the 112 leading points by never leading. The second pilot
receives 819 points, losing 181 speed points, but not losing any leading or arrival position
points. It seems to be all about flying fast, and not much else.

Our final case:

Case 5b.

The second pilot has to wait for the second clock but he is fast enough to catch
the first pilot half way through the task and they fly together getting to goal
together after that. The second pilot receives 965 points losing 35 leading
points out of 112. The first pilot receives 819 points losing 181 speed points
but no leading or arrival position points (obviously one or the other of these
pilots is actually going to arrive first and take the position points). So much
for leading.

Again we see that leading points are a shared resource and that even those who
don't lead get them. Next we compare these leading bonus point cases against
what they displaced, departure points.
