Day T is not set at all. That is a idea.
The rate increase is set, not target date.
1 satoshi is not a final target - it is not even a target, it is just an ordinary exchange rate somewhere in future. Next week will give 1.2 satoshi. Another week - another 20% increase etc.
1, 10, 100, 1000 satoshis per DVC to be a reached someday with gradual exchange rate increase. But without any deadlines. Rate increase can be slowed down over the time
I think the rate increase idea would be a fundamental mistake. Not sure how else to explain why so will leave it at that.
