error in timing with pause command

Hello Everyone. I have a weird problem with the pause command on a 12F675. This code snippet should make GPIO.4 high for 10 seconds but only goes high for less than 8. I'm using the internal oscillator like I always do but never had this much error in timing. Any ideas? Thank you.

High GPIO.4
Pause 10000
Low GPIO.4
Pause 100
