I do this a lot.
Most of my training during the work week is in small bites during breaks in my office. I get up and do a set every so often throughout the day. I use 24kg at work because I can't use chalk at work and I don't really want to break a sweat. At home, my working snatch bells are 28 and 32.
For snatches, I've done it two ways.
One is A+A style, but in small blocks, such as sets of 5 on the minute for 4-6 minutes.
The other is longer continuous sets with one hand switch, anywhere between 10R/10L and 20R/20L, often waving the length from set to set and day to day. The longer sets are harder, but they're spaced out with long breaks in between.
I usually end up doing about the same total volume per day either way, anywhere from 80 to 200 reps depending on how I feel and how busy I am.
Both seem to yield good results, based on how I feel when I do longer sessions with heavier bells and when I play full court basketball. The grip work from the longer sets has better carryover to my grip with heavier bells and longer sets, as would be expected.
