My understanding of `numprocs_start` is that it merely tells supervisor where to start numbering; i.e. 

```
numprocs = 3
numprocs_start = 3
```

would result in 

```
app:03
app:04
app:05
```

Also in my local supervisor, if `numprocs = 1` then it doesn't create the `:00` suffix, so I think this line can stay as it was?
