Should I change my SQL initial size to ward off frequent growth events?

I'm wondering if it's prudent to adjust the Database "Initial Size" value for my environment?
SQL version:  2014
Recovery model:  Full
Database Size:"   158GB

I recent ran a utility which indicated to me that: "89 growths took more than 15 seconds each. Consider setting file autogrowth to a smaller increment."
Autogrowth / Maxsize setting appears to be default of:  10% unlimited, and we DO see unexplained performance issues on this database.
Does it make sense to calculate an anticipated DB size,(for say, 1-3 years down the road?) reset Initial Size to that size, and keep the autogrowth setting as-is?
I've also seen on Microsoft's site that the growth % should be about 1/8" the size of the database...Should I change autogrowth from 10% to around 13GB?

Thoughts?
