    Normally different float

    Normally different float values (not necessarily negative), in a sequence of activities, depends on different calendars inside the schedule. 

    This always happens and is not a problem.

    From the following figure you

    From the following figure you will find that no matter what definition of float you use, start float or finish float it is possible even when using the same calendar that some activities can have lower Start/Finish Float than the summary bar while others show more.

    Summary bar aaa has a start float of 10 while activity a1 start float of 15 and activity a3 have 0 start float.

    Summary bar aaa has a finish float of 5 while activity a1 finish float of 15 and activity a3 have 0 finish float.
