I need a formula to calculate time units for concurrency issues and for
descrepancies in an audit. What I need below:

1.) a formula to calculate the minutes in 10 and 15 min incriments.
This formula should divide minutes by 10 & 15 min incriments. We then need
it to round to the tenths, for specific insurances such as: Medicare.

2.) a formula to capture concurrency issues. (when time overlaps per provider)

We use a db spreadsheet for this.

Example: Pt had surgery. Start time: 7:30 Stop time: 8:45. total mins: 65
Formula we had been using until we discovered that it did not round to the
tenths when needed. =+A1/15

Does anyone have any suggestions?
