In The Glorious Dead the Master states that immediately after passing through the Eye of Harmony he gained his powers to control the TARDIS, so that does mean that Izzy's adventures with the Doctor leading up to The Glorious Dead specifically take place at the start of his adventures, and that is why I reverted the edit.

Why the Master is in the TARDIS in the EDAs is a discrepancy which can't be reconciled with anything but speculation, but the placement of the comics (at least up to The Glorious Dead) can be asserted as taking place near the start of the Eighth Doctor's life. That was my argument about it all, really.
