1, for the zero momentum surface - I'd better do the sampling on two leaves separately.
2, for the high density along orbits - I don't think wavepacket is sufficient to explain everything (the 2nd-order approximation is very inaccurate, and base everything on an expansion-contraction balance sounds shaky to me). I think some diffusion argument can be made - so we know how to calculate the relative intensity.
3, for the fraction of regular trajectories - that result should be double-checked. I need to look into the high energy limits, and plot a few fLI vs. time to see if it is logrithmatic or linear. If no concrete results can be found, I will drop it.

I am proud of myself today
This afternoon my college classmate called me on MSN and asked if I had any ideas that can help with the current rescue work in Sichuan. He told me that he had connections so my ideas can be actually passed to people on the frontier. I supplied mine: to use truck tire tubes or air bags and either compressed air cans or even manual pumps to elate them underneath the fallen concretes for gradual lifting. I knew some basic facts about tires and I did ballpark calculations to find this idea actually quite feasible.
Later this evening when I got back on MSN my classmate told me that his connection thought highly of my idea and it was already passed to the people in charge.
I literally burst into tears, for that my ideas might be able to actually save lives. I never felt so proud of myself.
Update on May 19, I am really really happy today:

Possible thesis title?
The dynamics to localization in high-dimensional multi-well systems: a comparative study

Why being patient or why not?
Our subject is a wolf. He is thrown into a world comprised of sites. There are two kinds of sites: easy sites, where a rabbit is coming every T1 hours, and hard sites, where a rabbit is coming every T2 hours, T2>T1. The wolf knows that the density of easy sites is p, 0<p<1. How long should the wolf wait at one site before he decides to move around? Some extreme cases: if T2=infinite, the wolf should wait no longer than T1, and if T2=T1, he should probably just keep waiting. This decision also clearly depends on the value of p. For example, if p is 0, the wolf is better off just waiting. Note that the same strategy doesn't apply to p=1. This can explain why different animals have different behavioral patterns in terms of patience; it is an adaptation to their individual environments.
Some preliminary results show that, after waiting time of T1, the wolf is better off moving if p>T1/(T2-T1), and he should keep waiting otherwise.
