The total amount should not come close to 26m because over the year of POW there will be X amount of POS blocks.
Yes, this projection is left over from the original plan to have the first mining phase PoW only, which was abandoned due to negative community feedback.
As PoS blocks are less predictable, because the number of staking wallets plays into the formula, thus, the length of PoW and the number of coins generated cannot be as easily projected with any certainty. It is safe to assume these numbers will be halved from the PoW only projections. Meaning, ~6 month PoW and ~13 million generated. The original numbers would still hold true as a maximum if no wallets were staking which, is not the case.
We do appoligize for the confusion this has created. As you may know, the PoS/PoW mining phases were debated up until shortly before launch.
