This sounds a bit like it might be a VCL question, which would be
better asked in the  .vcl.components.using  group.

If Adam's answer isn't what you were after, then...

You might check the registry entry
HKEY_CURRENT_USER\Control Panel\Desktop\WheelScrollLines
to see what the setting is.
I would advise against changing the value because changing user
settings tends to anger users.

You might be able, though, to count the increase messages and divide
by the scroll rate before changing the control. (Like change the
control once every "WheelScrollLines" increases)
