1929 Ulster TT Race Programme

with those given in this table, it is possible to see which cars
are running ahead or behind their handicaps. Thus if a car in
Class F has taken three hours for fifteen laps, the time allowed
by the handicap being 2 hours 47 mins . '12 secs ., that car is obviously
nearly a minute per lap slower than its estimated speed . Again, if a
car say in Class D has taken 3 hours 50 mins . for twenty laps, the time
allowed by the handicap being 3 hours 56 mins ., that car is beating the
handicap, and gradually gaining on the cars ahead of it . By thus
checking the times on the score board it will be possible to decide which
cars are making the best running, and which are likely, therefore, to
stand the best chance of winning the race.

The problem of keeping spectators informed as to the progress of such
a race as the Tourist Trophy Race is an urgent one, as unless it is possible
to see almost at a glance the exact position of every competitor at any
moment, then the race becomes chaos as soon as attention is relaxed
for an instant . The problem is somewhat complicated for this race by
