Edgepro is excellent at setting a repeatable angle on a blade. However, the ability of the device to hint at angle changes based on the thickness of the blade. As such, use of a digital angle cube is warranted if you want a discrete number. Without an angle cube you can hit ballpark within a standard deviation or two of the angle markers. If the angle number is not important, it will give you feedback about whether you are hitting the edge or thinning the blade. PM me if you want to have a discussion.
As far as maintaining a constant angle isn't the Edge Pro fundumentally flawed. As soon as you move the stone away from the center line the angle will decrease, that is basic geometry. The further from the center line you work the more the angle will decrease. The distance fom pivot to blade is increasing, the distance from base of pivot to blade is increasing but the height of the pivot remains constant, hence a fundamental flaw in the design. This could be corrected by having the pivot rise on ramp as it was swung away from the center, ie. the further from the center the higher the pivot would rise to maintain the correct ratio beween the sides of the created triangle. Based on this it is not possible to maintain a constant angle unless I am wrong and the pivot already moves up and down as the stone arm moves sideways in which I apologise for my post here.
