I will move it a first time on Tuesday evening (at about 9 pm gmt) and then I will move it to the right time on Wednesday evening (at about 9 pm gmt).
So next week you'll be able to do 2 caps.
You will have one day to do the first cap and the usual whole week for the second one.
And of course, because of the shift, you'll have one day less to cap during the current shift.
Was I confusing enough?
