Blogger's Best Guesses on Timeline

Milestones (not official)
Estimates^  are just this Blogger's best guesses 
Deadlines# are worked out from the SPA. 
Latest is SPA timeframes including extensions (if any)
Actual refers to Date of execution

Note:

• I have not factored in the LTA Application & Approval because it's not in the SPA and besides, it does not make a difference to the long-stop date of 7 months + 1 month from SPA Date
• Deadlines do not mean what you think. The deadlines are not there to protect us, they are there to protect the Buyer.
• Long-Stop Date: 'If the Developer fails to rescind after the deadline passes - the SPA continues to be in force.'  I read this to mean the SPA has no end date and the Vender (us) has no exit clause.
