I get that. It's all good its better to be safe than sorry! And I completely understand why everyone says the 5 degree down thing! Its because they are welding the perches from the top. So the rear is upside down. So it is 5 degrees down. So when you flip it back over its actually 5 degrees up. See I'm learning! Haha I get it now I completely understand it. I just dont understand why I'm getting different readings I'm gonna try it again tomorrow when it's not pouring rain and see what I can get but I think I'm just gonna weld it at 5 and call it done.
