I am building a Lancair 360.

I just permanently bonded the Horizontal stab on. I took every precaution to get it within the 1/2 to 1 degree of negative incidence that Lancair specifies.  I used the water level to come come up with the proper incidence based on the plans.  After cure I recheck my incidence and Im 99% sure I have somewhere between .09 and 1.3 degree of negative incidence

My question is:
If the Horizontal has more than 1 degree of Negative incidence, say 1.5 or higher,  how does that affect the flight characteristics?    And vice versa if it doesn't have enough negative incidence what does that do to the flight?


Thanks
