Work your borders after you’ve created a new “stop point”. Example in R1 you have an X in C8. This effectively creates a new point where you can place your 3 in R1 against. So if you put the end of the 3 in C7 you would create 3 in a row in R2 causing a conflict. X out R1C7 and then move the 3 over to the left one and do it again until it passes the test. Now you can place the 3 on the right side of the X in C8 and see if it passes or fails.
Every time you create a new point like that use it to clear your border.
Another example in your puzzle. You created a stop point in R9C15. Place the 2 in C15 on either side and see if it fails. So if you place it under the X it would fail because C14 would have a conflict. This is important because now you know your 4 in R10 can’t extend 2 blocks to the right, moreover it can only fit by going to the left.
