As promised I uploaded a simple benchmark script for excavator - https://github.com/nicehash/excavator/blob/master/excavator-benchmark.py

Python 3 is required!

Examples:

1. benchmark algorithm 1 on device 0
python excavator-benchmark.py --excavator path_to_excavator -a algo1 -d 0 -b

2. benchmark all algorithms on all devices
python excavator-benchmark.py --excavator path_to_excavator -b

3. benchmark on nicehash pool (default is eu server)
python excavator-benchmark.py --excavator path_to_excavator -u btc_address

Default time for benchmark is 300 seconds per algorithm, you can modify it with -t parameter.
