The fix sounds reasonable--stretching out the response time to prevent the fault protection system from triggering a reset from what are presumed to be very transient alarms. They're proceeding with extremely prudent caution & diligence, though.

'Desensitizing' an FPS response must be done with great care just in case this transient condition isn't behaving precisely as they think it is based on ground modeling. Gotta be pretty confident that allowing the condition to persist longer won't do real damage (possibly in unexpected ways) before making such a change.

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
