How to make a spinning wheel in SL (no JS need)

Hello everyone,

Thank you to Chen for sharing this wonderful wheel of chance.

After several tests carried out with colleagues who need it for random question selection, it appears that sometimes the wheel number is not within the defined ranges and therefore does not appear on the sign.

Chen, could you explain how you define these ranges?
How can we know that for a single draw, the number displayed on the sign will be correct?

Why is the initial value 3409 and not 0?
Would starting with a starting value of 0 and an ending value of 9999 with a rotation of 3600 increase the number of possibilities for the ranges?
How do you calculate these ranges?

Have any of you encountered this problem when keeping the initial file (with the 6 sections)?

Thank you for your help.
