Actually, I have both sets of dates - they are generated automatically when I upload a start to the server. I did consider publishing the new ones, but decided against it since having two sets of dates, however carefully explained and separated would lead to confusion and acrimony. After last month I have gone for simplicity. You will have to content yourself with my assurance that the differences do not materially affect the Gold Laurel competition, and since everyone is playing the variant, will not affect the Green Laurel competition either.
FWIW, apart from SGOTM1, the Jason "values" for the SG games have all been different to a minor extent from the original GOTMs, and I decided from the beginning to stick with the original.
In the future, where old maps are "revisited" it would of course be possible to play to the new parameters which take account of any changes I make. I would invite discussion of this.
