You were quoting and replying to my post, so if you would like a proper response you'll have to be clearer with your question.
If your question was about why Ofgem hasn't published its July price cap if the price observation window has already closed, then it's because while the observation window for the futures curve is the wholesale component of the price cap, but other things also need to be calculated like supplier operating costs, EBIT allowance, the direct debit uplift, CfD, the levelisation allowance, VAT, etc, before the price cap is finalised.
But as it happens, the Q3 price cap was published at the end of May anyway, it'll fall 7% on average, equivalent to an average annual drop of £122 to £1,568.
