Follow-up date calculator
Every gap measured from the first message, so a late send does not push the whole sequence out.
Comma separated. Counted from the first message, never from the last one.
Why measure from the first message
If day three slips to day five and you then count seven days from there, the last message lands on day twelve — by which point the thread is cold and you are still, technically, following the plan. Anchoring every gap to the first send means a late message costs you that message, not the sequence.
