So there's a couple of considerations here. Firstly, to capture the fast motion in your particles you need to reduce your sim timestep and also enable cache subframes in the Cache rollout. That will properly transfer the fast motion to your particles. However, the Export Particles operator only sets whole-frame keys on exported particle transforms. That's an oversight on my part...I will make a note to have it export keys on subframes if the sim has a subframe timestep. The next build should be out soon, so check for that update in v1.106.
