The 100 hours really surprised me. The rules are different for each round, but least for my team in the second round we have not had to spent that much time on it. We probably spent no more than 30 hours and that is generous. However I guess it depends on the type of company and the kind of expenses.
Overall I have found people's perspective on the program depend entirely on assumptions and expectations before they arrive. If you expect a suitcase of cash when you land, if you expect all the processes to be pre-arranged, if you expect to never have to deal with any bureaucracy, you will be in for a surprise. If you expect lots of opportunities to network and get connections, if you expect that the government will throw the odd curve-ball now and then, then SUP will be what you expect.
Me again (Round 2) - I spent 2 days doing the first reimbursement (following instructions, taking advice from Round 1 people) and then 1 day or less for each subsequent monthly meeting (including having the meeting). Write-up from a few months back:

All in I'd expect 1-2 days per reimbursement meeting (including meeting time), less as you get better at it, less if you reimburse just a few big things (rather than lots of small stuff). Cash payments require less proof (less paperwork) than debit or credit cards (CCs require most). That's about all there is to it.
