Android Question Screen Burn fix

[GaryK4]

I have an app that I display a distance & time as a screen saver. However, I am still getting screen burn. Every 4 seconds, it displays in a different location.
xv.AddAll(Array As Int(10%X,15%X,20%X,25%X,30%X,35%X,40%X,45%X,50%X,55%X,60%X))

I would like to make it more random (n=2 to n=60 incr 2 or 3). I don't know how to convert n=2 into val = n%X.
Also, is there a better approach?

Two options:

Dim x As Int = PerXToCurrent(n)
Dim x As Int = n / 100 * Roow.Width
