I post my data to a 'report' table.
user picks the date range on a form, then queries post the data:

id, currTime, prevTime,currAmt, prevAmt, pctChg

after the data has posted for each time range, 1 more update query runs to post the PctChg.

add an autonumber field to your table:

see Query1 on the sample.
