Simulation problem !

[george]

Sometimes when i hit simulation in Summary History i see something like increase[49%] and i don't know how to interpret this...

This is normal or is a bug ?

that's normal. it may happen the count of simulations that lead to an increased value is very close to the count of simulations that lead to decreased value. for example 49% simulations caused increased history value, 47% caused decrease and 4% simulations generated the same history value.
