1) P levels are probability

'An example of probability as believe is the common use of probabilites P10, P50 & P90 to describe the range of NPV results from a large number of reservoir-economics evaluations obtained by varying input paramaters with each trial. The NPV of an actual reservoir under development conditions modeled is a set but unknown value. Probabilities expressed as degrees of belief always depend on the available information. Based on what is known about the reservoir that NPV has a 10% probability of being at the P10 model result or less, an equal chance of being greater or less than the P50 median and a 90% probability of being a value less than or equal to the P90 prediction.
