From a technical point you don't want to reduce intel too much, of any type. The reason is that intel works in a grid-like fashion, even though all range rings are rendered as perfect circles. I recall there was an image by @Hdt80bro to illustrate this perfectly, I'll update this post when I find it

The chunk of red walls is copied on the right, but then with intel taken into account. There's a deceiver (stealth field) in the center of the right 'chunk' of walls. There's a few interesting observations to make:
Intel is grid-based
The cells of vision intel is 2x2
The cells of other intel is 4x4
And separately, intel is updated every 3 seconds or so. That is why fast moving units (such as scout planes) do not 'immediately' see the units, but they appear 'below' the scout as it moves over previously unknown structures
