Thanks for your answer, but now I'd like to know whether it is possible with your program to divide the fractions in two different sections made of 5 people. We are 10 people on 4 lanes and normally your program creates a unique fraction in which we run one after another. We need to pause between the sections, we'd like to have a section in which 5 of us run, then another section in which the remaining 5 run. Is it possible with your program? I know this is slighly difficult to understand, but in Italy we usually do not run all one after another, but normally divide the run in two/three moments in which just a group of us run, then another group, then eventually the last one, and so on.
