Your mention of the T5 indicates that you were refuelling Mk6 jets.
We did it in the F3 without the big ventral. Our biggest problem was if any of us needed to use the p-bag.
It took about six hours because of the speed limit of the drogues. If I remember it was 250 kts IAS. In my day the tankers would not accelerate between brackets quoting that it made the navigation easier.
