But 2 Spring effects with different offsets and non-zero effective
force can't be combined into a single slot (without streaming them
with Constant force), right?

OK, is this method used when all force-slots are already full?
Or is it only used for some specific (restricted) devices, such as
devices with only 2 force slots?

And in this case, is the position of the device monitored at a speed
higher than 8ms, in order to keep the feedback-loop stable?

Thanks,
Elias
