I have tried the calculation and layout of year 1998, and have some confusions as follows:
1. Usually in non-stopping calculation, we leave 20% contingency. But I noticed people do not leave contingency when calculating stopping headway. I think it should also leave 20% contingency although I did not do so in this practice
