“I've just had these fitted too and have to say they seem much quieter than my Kumhos and certainly dry grip is excellent ( though I don't tend to drift round corners, unless something has gone wrong!)”

Higher is better. The Relative Score follows your weights below; category scores do not change.
Wet grip starts at “Important”. Treadwear starts at “Neutral” here: road tests measured it for at most one of the two tires, so it rests on owner reviews. Move the sliders and the scores update instantly.
Only one of the two tires has a score here, so this weight changes nothing in the head-to-head.

“goodyear efficientgrip performance notches Hello! I bought a new goodyear efficientgrip performance 215/55/18 tires for my car. And it was surprise to see so many notches on the summer tire (1st & 2nd photo). Although the internet image doesn’t have any (3rd photo). What could it be and is it normal? Read more”
“FWIW the Goodyear EfficientGrip Performance 225/60 R16 102W XL tyres arrived and were installed today. The difference with previous tyres is like night and day. I have a 1200 km work trip later this week and I thought I'd take the Benz out. Interesting to see how they "break in" and how much if at all difference there is in mpg.”
“Wet Braking Demonstration FlexContact Tech in the EGP series tyres implies the use of a new polymer tread compound for better grip in wet road conditions: For demonstration, we again had a GLA shod with Goodyear EGP tyres. The car would do three runs on the main straight and brake to a halt on an artificially created wet patch. After each run and subsequent halt, the braking distance was recorded. The braking distances between the 3 runs on the Goodyear tyres were averaged to 24.5 meters from point of braking to an absolute halt: Thereafter, the EGP tyres were swapped for a set of Continentals to do 3 identical runs in order to draw a direct reference point: Care was taken to maintain the wet patch in identical conditions by making use of mobile mini-tankers parked along the track: Panoramic alignment gone bad! Soon enough, we had the GLA ready to take on the wet braking test with the Continental tyres. The car averaged a braking distance of 25.5 meters from point of braking to an absolute halt:”

Neither, by our numbers: 64 vs 63 on the treadwear score, within 3 points.
Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.
Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
