+The selection process SHOULD be designed such that
+on average the spin bit is disabled for at least one eighth of network paths.
+The selection process SHOULD be externally unpredictable but consistent for
+any given combination of source and destination address/port. For instance,
+the implementation might have a static key which it uses to key a pseudorandom
+function over these values and use the output to determine whether to
+send the spin bit. The selection process performed at the beginning
+of the connection SHOULD be applied for all paths used by the connection.
+
+Note that where multiple connections use the same path,
+the use of the spin bit MAY be coordinated by endpoints,
+recognizing that this might not be possible in many cases.
+
+When the spin bit is disabled, endpoints MAY set the spin bit to any value,
+and MUST accept any incoming value.
 

So the proposed text would be:
```
When the spin bit is disabled, endpoints MAY set the spin bit to any value,
and MUST accept any incoming value. It is RECOMMENDED that they
set the spin bit to a random value either chosen independently for each packet,
or chosen independently for each path and kept constant for that path.
They MUST accept any incoming value.
```
