Dates for milestones
Yip, I agree.
In the date column we should use the date when the projects became real -- not the intention. We can always include a clarifying note or reference in the details section refering to earlier dates of key milestones.
For example, that date that Otago Polytechnic took a Council decision to establish the OERF in the details / clarification section, where the date that the OERF become real, i.e. the date on the certificate of registration.
