I see now that the model approaches a finite limit at the first data point, and so it can be "rescued." Giving good initial values has come up before, as I recall, but I couldn't find it just now. | |

"You should (always?) evaluate your model on your data..." - since FindFit[] will be doing that anyway, quite likely many times, you will want to do this sanity check first so that FindFit[] won't waste your time.
