In my case, we have two other attendant care providers for our son, it can be tricky to calculate how many hours they will be working ahead of time. Sometimes those attendants work more or less hours than scheduled which effects how many hours are available for me.  My son requires 24 hour care, if I’m not physically with him, there is another attendant clocked in.  There is less room for error if I enter my time at the end of the pay period after the other two attendants have entered theirs.
