Two things:
1/ Intervals: If the switching was instant, you would be making most out of a short interval in theory. This is because, as said, you'd be nimbler to jump on whatever coin is most profitable at any point in time. Unfortunately, miners take time to switch. There's an initialization phase, every gpu starts up, sometimes it takes over a minute to get all your cards hashing. This is inefficient. So you can even this out by forcing your miner to stick around a bit longer per algo. I however do not believe you'd be doing yourself any favour by setting intervals longer than 10-15 minutes because you then lose that flexibility.
2/ Stability: My rig (5x 1080) is crashing several times a day with Nemosminer. I'm talking once an hour on avg. That's not good. On single coin it chugs along perfectly fine without reboots. I haven't yet been able to pinpoint the issue, so I can only *guess* either one instance of ccminer is unstable or the switching causes it.

Could be power related as when I first start mining on my 5 x 1080 ti rig with 1500W PSU and I noticed the cards will use full TDP briefly and it will do an impromptu reboot.
Never happens with EWBF but other miners can do it in the first minute or two
