I'd be interested to see how it compares to the "proper" video-based measurements!

I'll help you make an official report over the next few days. We should be able to accurately determine the length of the occultation to a high degree of precision and that is still a very useful observation. Of course knowing the exact time is even better, but duration only observations are fine.
Using video, its possible to determine the time of an event like this one to one fiftieth of a second, but software tools allow drift occultation's like yours to get a precision not too far off.
Can you PM me your exact lat/long and your email so we can get your draft observation plotted!
