Thanks for posting the videos! Your aggression level is improving, but it looks like you are driving "one element at a time" instead of linking elements together. When you know what's coming, you are aggressive on the throttle. But there's a lot of coasting in between elements. That course had several areas where you could have anticipated the next element and you could've been "fast out" of one into the other. There are several areas where you are clearly very comfortable and some areas where you seem to lose the course for a moment, just long enough to hesitate. You are also moving your hands on the wheel quite a bit. I tell novices that every time you take your hands off of the wheel, you are losing time. There are some times when it's necessary, but there appeared to be several places on this course where you moved your hands on the wheel when you didn't have to.
The best way to bring your throttle inputs closer together is to link elements in your attack strategy. I do 4-5 course walks before I lead the novice walks at my events. I make mental notes about linking elements, especially elements where I have to think around corners with bad sight lines.
As you walk the course at your next event, stop at the exit of every element and look ahead at the next 2 elements. Look for hidden straightaways, or areas where the next element (or elements) is fast. Doing that allows you to see what elements are "fast-into-fast-into fast", which becomes "this SECTION is fast."
All the work you've done to improve your fundamentals is showing up in your runs. Which is great! The next step is to capitalize on those fundamentals by attacking longer sections of the course.
