Greater forces than IRL? Why?

What size is your wheel btw?
With a 28cm wheel I ran about 60% base strength, with a 32cm wheel I ran about 90% base strength of my csw 2.5 (8 Nm)

Ha! I hadn't even considered wheel diameter.

Yeah, I'm running an Ascher F-28 also - and my other wheel is 270mm. I didn't realise how much more torque it would make over a slightly larger wheel! I run mine at 60% in-game with the Simucube software at 100%.

Mystery solved - thanks Rasmus

Hehe glad to be of service

An example:
To hold against a steady torque of 10Nm, you would need to pull (1 hand) with 10 Newton if you'd have 1m leverage. That's about 1kg.

So with 28cm diameter, that's 0.14m leverage per hand.
So 10 Nm = 0,14m * X (and diveded by 9,81 to get kg):
X = 7.3kg
But since you have two hands in the wheel, it's only 3.65kg.

Holding 3-4kg dumbbell in the position where your wheel normally is pretty tough imo!
Luckily it's not constant and it's alternating between pulling and pushing.

With 27cm diameter it's (10/0.135)/9.81 = 3,78 kg per Hand.

Not THAT much difference but many of us have a formula wheel with 27cm diameter and a 32cm round wheel.
That's 18.5% bigger.
