##### SUMMARY Replace the constant poll interval of 1 second, with a truncated exponential back off algorithm with jitter. Below is a suite of poll interval (in seconds) generated by the new algorithm: ``` 1.49 2.14 5.46 6.51 6.57 5.57 5.98 7.13 6.59 7.10 5.54 5.03 6.56 5.96 6.72 7.21 7.05 5.31 5.60 6.33 6.82 5.42 6.08 6.60 TOTAL: 140.77 ```
