New to statistics, would appreciate any advice you can give :)

Doing forecast accuracy, and looking at using MAPE. I have data where most of the time my actuals are 0-15% below, and 0-2% above. Is it legit to split out my data so that a MAPE is done separately on the positive and negative?

It'd be nice to say I have a forecast of 92.5 +1.3/-7%, with an overall MAPE of 5.5%.

Or does splitting it out not a correct application? Thanks so much for any help!!
