Regarding cross contamination of 87 with 91 octane, you've similarly dismissed the learned advice of other posters.
For fun, I did the math. If the car before you filled with 87 and you then loaded a 1/3 tank of 91, the net octane resulting from the 'cross contamination' would be in the area of 90.95. With the knowledge that owners deliberately or accidentally use full tanks of 87 on their Jags with no known damage, I doubt running on 90.95 will cause much of an issue.

Many F-type owners chipped in stating unanimously 'there's no issue with E10'. Not one instance of a Jaguar (any model) was offered up with evidence of damage. Nonetheless you maintain your stance that there's 'issues'.

My concern is I don't know how much low grade fuel remains in the line before high grade fuels begins to flow. The dispenser line is at least 3 m long with a diameter of at least 25 mm resulting in 90.88 octane after blending (assuming a 20 L fill). I agree that seems trivial. If the actual volume of 87 is larger (not knowing where along the system the switch between 87 and 91 occurs), then I'm concerned. I was hoping that a engineer who designs fuel dispensing systems would weigh in. In the meantime I stick to my fuel quality fueling method (as odd as it is lol). I was also wondering if others do this or am I the only crazy person in the F Type world (it appears I may be).

A simple Google search provides the answer- direct from the horses mouth
Am I getting hosed by regular at the pump? - The Globe and Mail
"Shell says that, as long as the premium purchase is more than 10 litres, the total sale will be “on-spec for octane and meet the 91 AKI standard.” It added that Weights and Measures Canada, which monitors and inspects pumps and controls the related regulations, approved the use of “single hose blender pumps” many years ago."

"Many F-type owners?" You don't even have one, so you don't count. "Unanimously?" Hardly, just you throwing tantrums and refusing to consider overwhelming mount of evidence, because "look at me, my old Chevy is fine, look at that fine picture of gas cap".
Here is another recent article on harms of ethanol from your favorite newspaper:

Speaking of trolls........
Here's the inside of my old Corvette's gas tank. It's had nothing but E10 since the mid 90s (20 years) and is stored for 6 months of the year over our Canadian winters in an unheated garage. The gas you're seeing was 2 years old at the time.
There is no corrosion. There is no water............

So what happened to the old one, when did it rust out?

The unit in there now was offered to me by the OEM at a very low cost (almost free) as they were looking for a 'mule' to test fit their line of replacement tanks.
It was manufactured from plated steel following GM OEM processes. No stainless, no magic, no trickery.

So inside your old Corvette's new gas tank it looks like new. Everything else aside, don't you think it is A LOT misleading to repeatedly post a picture of it, implying it is original?
As an aside, when I looked inside tank that failed at the seam due to internal rust, I couldn't visually see any rust even when I knew where it was leaking. So in cars that are driven, you can't really visually see rust until it fails.
On other hand, another car I have is equipped with a swirl pot contraption (what a bad design). The tank is 100% fine, but due to swirl pot it looks like there is a lot of rust in there.

Also not mentioned, is that this car has an 'open' fuel system where air is freely permitted to enter the tank via the cap to replace fuel as it is used. This is in contrast to today's cars where the caps are sealed and no free movement of outside air is permitted.
As mentioned this fuel tank has had nothing but E10 since it's installation.
As such- if there's any vehicle that should have suffered from the ravages of ethanol, this would be an ideal candidate.
