... Unless you want to shoot sequences like this.
Continuous burst of 5. At a slower burst rate, I'd have missed the critical moment.
These moments are nearly impossible to follow with our human eyes. I track swallows (as best as I can) and if a swallow changes course abruptly, I squeeze a burst. It's a fairly reliable way of capturing a feeding sequence. Since getting my OM-1, my success rate has shot through the roof!
