guard probability for all guards having ORPort on 80 or 443: 
45.99%


guard probability per ORPort:

+---------+-------------------+
| or_port | guard_probability |
+---------+-------------------+
|     443 |              44.4 |
|    9001 |              39.1 |
|      80 |               1.5 |
|    9002 |               1.3 |
|    8080 |               1.1 |
|    8443 |               0.9 |
+---------+-------------------+

unfortunately onionoo does not have fallbackdir data, so I can't
provide the same table as above for fallbacks without
creating it myself first
