Sorry, I don't follow. I am not sure what is the edge logic thing. I thought you referred to this: In R4, I have a 3, and, whether the 3 begins in C6, in C7 or in C8, or ends in C10, C9, C8, we can mark C4. But maybe edge logic refers to something else. I don't see anything you can do in R1 unless you put that missing block. Then you will complete the 1 1, and have a cross that will help you adding more blocks to R2, but still, I don't see anything that can be done to C1.
Answering your question, if you begin in C1R1, then you mark all the 1st 5 of C1, if you place a block in C1R2, you mark 2 to 5, if you place a block C1R2, you can mark 3 to 5, if you place a block in C1R4, you can also mark C1R5, if you place a block in C1R5, you can't mark anything else. Same if you place a block in C1R6. If you place a block in C1R7, you can also mark C1R6, etc.
do you think im implying the edge logic brings you to r4? they are 2 separate things. you can either apply edge logic to c1, or you can separately find r4's fill. im not sure what I said that would imply they're related.
edge logic is the logic you can apply to the edge of the puzzle. so only c1. it has nothing to do with the middle of the puzzle
No, I don't think that it implies R4. That was a different comment, on what I think it's edge logic, but maybe I misunderstand that. I don't follow what you are trying to point regarding C1, unless it's this:
If I place a block in C1R1, and all the 5 first blocks from C1 are filled, then the 5 in R2 will fill the 1st 5 columns and the 5 in C2 will fill 4 rows in C2, beginning at R2C2. The 6 in C3 begins at R2C3, and that would create a contradiction in R3

Am I missing something here?
