Summary: Batch startup options unintuitive and don't work as intended

Initial Comment:
There is a timing problem when I check "Introduce
Virtual Users in Batches".  This is most noticable if
I'm starting VUs no faster than 1 per second.  If there
is more than one batch, then the actual batch ramp up
time is less than what I specify.  The actual ramp up
time is "(specified) ramp up time" divided by "number
of users per batch" too short.

I'm running OpenSTA 1.4.3.20.

An example illustrating this issue is posted at
http://portal.opensta.org/modules.php?op=modload&name=phpWiki&pagename=TestBatchOptions&file=index.
Another problem mentioned there - the time between VUs
within the last batch is longer than for all other
batches if the total number VUs in the task group is
not evenly divisible by the number of users per batch.
