Help You Southern Guys

I just finshed turning a small grapefruit bowl, and will dry it using denaturated alcohol. I left the standard 10% in the wall thickness, but my question is how much warping do you think I will get with this grapefruit? As you can surmise this is the first piece of this I have turned. The tree was cut down this week. Thanks for your help. Glenn Hodges Lost in the woods in Nashville, GA
