question about normal heating cycles

Our new Gibson 92% efficiency furnace kicks on 10 to 15 times to bring the in house temperature up from 60 to 70 degrees. (The temp outside is 55 degrees). It takes about an hr to go through this cycle. Our installer says this is normal, it doesn't seem normal to me.

10 degrees is a big recovery. I would only set back 6 degrees max.
You're not just heating the air, you're heating the structure and the contents.

Post the t-stat model number.

If the stat calls for heat the entire time, your furnace might be tripping the high temp limit switch.
