I don't understand it either, but I know FFlag will exit and return true when the flag is no longer on the MM, because the flag disapears 3-4 tiles before you reach your point, SPS will continue to the next point early, theres also the time it takes to calculate position and then move the mouse there for a click, so if you want pinpoint accuracy, then you need to be completely still before moving to the next point (I find 1500ms wait after FFlag is about as good as it gets), theres also the 5x5 randomness of the point click in SPS and multimouse within it, if you look at my airorb charger, I edited all these to get it more accurate, but you still have to stand still for that split second to ensure accuracy
Theres also the fact Sps will exit if you are within 2ish tiles of your point, because it's not 110% accurate and position can vary by a few tiles,
Sps walking to a point, then waiting 1.5+randomness seconds, then using a DTM, is probably the only easy way to walk to an exact point, tho my air charger walkpathing got to be accurate within 1 tile around my chosen tile, which can be worked with most of the time,
Theres also the fact you can have your point 1 space into a wall ( say for in a bank like castlewars or etc, then Sps will click into the wall, making your flag/position exact to the bank tile, meaning you can more or less get 100% accurate results when a wall/sizeable object is at a direction of your position,
Accuracy of your custom map is also really inportant because the more accurate your position calculation, the better the walking results,
