I'm in Round 2, I've been giving feedback for months to the staff. The feedback I got today about changes they're making during Round 4 (for those just arriving now) is pretty impressive. If they carry it all off then the programme will be improved by a fair margin for subsequent Rounds.
The improvements are still under discussion but ought to address many of the mentorship/fund raising/expectation issues that have been raised (at least - I have cautious optimism that that's the case).
Disclaimer - I don't work for SUP, I'm almost finished here in Round 2, I've had my complaints during the programme but generally they're reacting/improving to the significant issues. Things are improving for every new Round.
