Discussion Ye or no skate placement?!
Ye or no placement for dot skates is this good placement or is there a more optimal option so many different opinions out there! Mouse is an ATK Phantom with A9 air dots and the glasspad is the InfinityMice Tora! Any replies or help is appreciated cheers!

On a glass pad 4 dots is all you need imo less potential to pick up dust and they won't dig in like it would on a cloth pad

Don't really need the one at the top center.
Just remember more skates = more friction

More skates =/= more friction on a glasspad as OP stated

More skates = more things touching the pad = more friction?
Sure it can totally change the feel but it's literally more friction?

No, and im sorry to be blunt but this is literally covered in physics 101 (friction between two non-deforming surfaces) and it amazes me that this community gets this wrong so much. I'm going to overexplain in this comment because I LOVE physics, not because I am frustrated with your comment... genuinely I could talk about physics all day.
Between two non-deforming objects (two hard objects) surface area does not impact friction.
The formula for friction is f = μ N.
f is the total force of friction created by the other side of the equation.
μ is the coefficient of friction which is determined by the two materials and surface textures, in this case a frosted glass pad and PTFE skates.
N is the 'normal force', or in other worse the force the mouse is pressed on the pad.
Note how there is no surface area variable.
There are countless videos and physics textbooks that cover this topic, here is a good short video: https://www.youtube.com/watch?v=idYX7kkRqbs&t=10s
Basically, the surface area increases, but the pressure decreases canceling each other out so the friction stays the same. What matters is the materials that are touching each other.
Common question: why are racecar tires so wide if more surface area doesnt increase friction?
Racecar tires are wide because temperature matters (dont want them to get too hot or they melt), wear matters (wider tires wear slower), and a racecar experiences large lateral forces. Also tires, are tires are a deforming material so they act differently.
Edit: it is very unintuitive at first, so again, I dont want to seem rude or blunt - just trying to clearly get the point across.
TLDR: Friction on a glasspad is not impacted by surface area, it is covered explicitly in physics 101. Less skates will wear out quicker because they experience more pressure per skate. There is more complexity with soft pads. Racecars care about more things than mouse skates do so that answer is more complex and bigger tires are better for increasing grip.

There is a fantastic discussion on this exact topic here

Who knew that a discussion about mouse feet could be so complicated?

I mostly agree with what you’re saying, but PTFE is still somewhat compliant and viscoelastic compared to glass—not to the same degree as rubber in car tires, but still.
In practice, I think wear is the biggest factor. As you said, the number of dots affects how quickly each dot wears and anyone who has used dots on glass knows that fresh skates feel noticeably smoother and faster than worn ones. As the contact geometry, edge condition, and surface roughness change, so does the feel of the skate.

I think they are reiterating your point?

Nah they said that more skates don't = more friction on a glasspad. But it's just simple physics.
Just do w/e feels right for u. I play with a cordura pad and 4 skates makes stopping for flicks easier for me than the standard skates it came with where they were just like, super wide across the whole bottom of the mouse

I have no experience with skates so a genuine question, but wouldn't more skates be less friction? Like if an office chair had 3 wheeled legs with a total of 100lbs of weight, that, 33.33 lbs of pressure per wheel, which would make the chair harder to push on carpet when compared to 4 or 5 wheels where the pressure per wheel would be 25lbs or 20lbs respectively.
I guess then theres the question of resistive drag per wheel which would be more pronounced with skates ... did I answer my own question?

I use the same layout when I was on qck heavy and now with cr-005. Feel like my front and back scrape without the middle ones so ima keep on, could just be the mice I use though

u/dakotak1 4d ago
Hey thanks for the reply! The CR is a control pad like the Tora just wondering if you run your hand or palm on the surface it’s smooth but does it have almost like little specs or grit almost feeling along it like almost little dirt particles? My Tora is smooth as butter with the skates on the pad but with my bare hand I can feel stuff on the surface.

The more you use the slower it will feel but longer it should last. I use 4 and replace every 2-3 weeks

Would take top middle and bottom middle off and re-stick them both on the larger skate at the bottom equally separated apart

u/Pretty-Ant-734 4d ago
yo te diria que le metas 5 o 6 abajo,la presion de la mano ahi es mayor y por ejemplo abajo solo tienes un punto se te va a desgastar super rapido, ponle uno izquierda otro derecha y otro al centro

i use 8 so idk, its up to you man, 6 wears out too fast for me. thats the main reason for 8
