Holes for  MPL3115A2 Pressure Sensor

I'm trying to use the MPL3115A2 barometric/altitude/temperature sensor in a model rocketry project. I know that I'll need to put hole(s) in the side of the rocket in order to get an accurate pressure reading, but I cannot find the size or positioning of those holes in any documentation for the sensor. Does anyone have the information I need or know where I can find it?

 

The rocket already has four 0.02808 inch holes at 90 degree angles, 4-5 diameter lengths away from the nosecone shoulder for a stratologger, which will also be collecting altitude data. Will those holes be sufficient for the MPL3115A2 sensor as well?

 

This is the board I'm using for the project, which uses the MPL3115A2 sensor.
