The following are some of the most commonly encountered values for the X/Y coordinates while attempting to clip

X1		Y1			X2		Y2			description
--------------------------------------------------------------------------------
AF		F/0/1		B3		2/3/4		bad lineup (-1.5 px)
B0		F/0/1		B3		2/3/4		bad lineup (-1 px)
B0		F/0/1		B4		2/3/4		bad lineup (-0.5 px)
B1		F/0/1		B4		2/3/4		clip
B1		F/0/1		B5		0/1			bad lineup (+0.5 px)
B2		F/0/1		B5		0/1			bad lineup (+1 px)
B2		F/0/1		B6		0/1			bad lineup (+1.5 px)

AD		D/E			B1		F/0/1		clip, positions logged a frame early
B1		E			B4		1			good lineup, but jumped a frame late

Lineup is essentially luck based, so the goal is to be within 3.5 pixels off of the good X coordinates, since Mario's max running speed is 3.5px/f.

Note that the ranges of Y positions that may work can vary:
- with a low jump (low 3x Y speed), F/0/1 on frame 1 then 2/3/4 on frame 2 should be good
- with a higher jump (high 3x up to 45 Y speed), E/F/0 on frame 1 then 2/3/4 on frame 2 should be good
Low jumps are recommended of course, but avoid having under 30 Y speed near the pipe.

Also, landing on the pipe gives a position of 0, or 1 for a frame, and that's usually logged on the 2nd frame.
