Boost spike or creep

Ok call me stupid...Whats the difference between a Boost spike and Boost creep?

My PFC is set for .85 bar but hitting a high of .93 after 6000RPMS

Your not stupid...what I take from it is that creep is when the psi slowly increases over your set/normal level. Spike is when it suddenly takes a jump and then returns back to the previous level. A friend of mine had a spike once, normal 10 psi it spiked at 14 psi.
