 The following guidelines are suggested for selecting these parameters for a soft fork:
 
 # '''name''' should be selected such that no two softforks, concurrent or otherwise, ever use the same name. For deployments described in a single BIP, it is recommended to use the name "bipN" where N is the appropriate BIP number.
-# '''bit''' should be selected such that no two concurrent softforks use the same bit.
+# '''bit''' should be selected such that no two concurrent softforks use the same bit. The bit chosen should not overlap with active usage (legitimately or otherwise) for other purposes.
 # '''startheight''' should be set to some block height in the future, approximately 30 days (or 4320 blocks) after a software release date including the soft fork.  This allows for some release delays, while preventing triggers as a result of parties running pre-release software, and ensures a reasonable number of full nodes have upgraded prior to activation. It should be rounded up to the next height which begins a retarget period for simplicity.
 # '''timeoutheight''' should be 1 year, or 52416 blocks (26 retarget intervals) after '''startheight'''.
 # '''lockinontimeout''' should be set to true for any softfork that is expected or found to have political opposition from a non-negligible percent of miners. (It can be set after the initial deployment, but cannot be cleared once set.)
