Si can also be like specific,just a rough example like if I do this at this particular time with this particular measurement, with this particular element, with this particular etc., it is more direct to the senses, harmony of movement and such. Like for example, Si will want to use a specific soft item to get a result, but may have trouble figuring how to get a better result without previous practical knowledge. Ne will deal more with alternative items that stem from the theory of why it could be used to get the result with a different item that is not particularly visible at the time. it matches up wih your idea. Like their are certain pressure points that reveal a hidden shape. That is Si sort of imagination fueled by Ne. If you are INTp - well I can't really make a case for that because I'm not conscious Ni or of how Ni works. All I know is that it is vague and prepares for events that could be developing on the whole. It's not in my conscious blocks so that is just a rusty idea of what it is. Even if I read it written by someone who knows Ni particularly well and I read it, it won't click at all in my head. That is the consequence of 'quasi-identical' relations I suppose. Either you could be INTj with an idea ahead of your time, or an ESTj who particularly uses Ne a lot or also with an idea ahead of its time. Alpha or Delta. If you need clarification I'd be glad to oblige.
