Care to elaborate? Because otherwise I can say "it totally is!", and we leave at that.

Basically, signals take time to travel. If it is ~.1 s, then predicting it that much earlier is just the statement that your computer has faster wiring.

However, if it is a minute earlier, we are forced to consider the possibility - even if we don't want to - that something contradicting classical ideas of free will is at work (though we can't throw out travel and processing time either).
