I am trying to think of a good function for calculating an initial wait time. Below is one possibility.
```
AT is the actual number of tablet servers
ET is expected number of tablet servers (configurable by user? what if AT>ET?)
EXP is a configurable exponent
W is the wait time in seconds
W = (ET - AT)^EXP / 1000
```
The image below is a plot of the wait times (in seconds) for 1,026 expected tablet servers with an exponent of 2.1.
