Hi, I'm currently working on the 250 box challenge, and I keep running into a few small questions that I thought may be helpful to seek clarification on earlier rather than later, just due to the sheer scale of the challenge. They also apply to other aspects of the course.

Some are perhaps inconsequential, but I figured I may as well see what others think.

1.) After 'missing' a point for a ghosted line, should I treat the end of that point as the new target point when drawing other lines meant to intersect it, or use the original? I tend to use whichever seems more correct. That is to say, whichever aligns with the vanishing points the best.

2.) When drawing line extensions, I sometimes run into lines that are curved for one reason or another, or in other words, they form an arc. I tend to draw the line extensions intersecting the start and end points of this arc. I imagine the arcing is sort of another axis of improvement different to that of my ability to connect two points. Does this seem like an alright strategy?

3.) When resolving the last three inner lines (x-ray lines, if you will), of each box, should I try to distribute the error evenly between the three vanishing points, or pick one of the points that is 'correct' for two VPs and let the third one take on all the error? Here's an example of what I mean, basically should I aim for the purple point or one of the red ones? This is how my mind conceptualizes it, at least.

Any input is appreciated, thank you!
