Source: We both agree Tesla has a 3-month, production cycle each quarter. My hypothesis: 1st month - review lessons learned from 3d month of previous quarter. Tweaks to production are implemented which often means the lines are down as needed. 2nd month - renewal of production getting sources notified of the impending production surge. 3d month - balls-to-the-wall, production benchmark. This is not only for revenue but to identify production limitations. Bob Wilson
