It would be interesting to know how "actual" event compared to the sim exercises prior to LST etc.
I know this is slightly of topic of E170 flap failures, but during the early years of CRJ200 operation, I did more 0 flap landings than I care to remember. The CRJ is a little dinky toy compared to the bigger iron (21.3 ton MLW), but it has no LE devices, so Vref(flap0) @ MLW is 178kts.
Two most difficult things about the landing is keeping the speed down with no drag while staying on the slope and then getting the bloody thing to touch down. It would float till tomorrow if you didn't force it onto the tar.
Landing distances for the CRJ were as advertised in the books, but I can't comment on Embraer figures.
