I have found it necessary to put the marks in the racecourse for each lap (eg. Mark1, Mark2, Mark3, for lap 1 and Mark1, Mark2, Mark3 again for lap 2, otherwise the analytics only works for the first lap. Is there any way around having to do this?

And in a 4 lap race with 6 marks I seem to be unable to add beyond about 20 marks using the above method……is that the limit to the number of marks I can enter?
