So.... aside from the absolutely useless debate on whether Standing, SH, FH jolts are better, let's try to get back to the topic at hand: Killing. Not building damage, killing.
I've noticed that I build up damage too fast and miss the Up-Throw->Thunder combo sometimes. I've been compensating for this by trying out D-Throw->Thunder, which works decently. It doesn't seem as reliable, but it's an extra option to consider.
I've also noticed that a lot of the times when Up-Throw sends up someone past Thunder, they're often at a high enough damage that just a well-placed dash attack can kill them. I think the real key to killing with Pika is remembering what to try to kill with if one of the usual setups don't work.
