Question about multicoin pools

[SixSignatory]

I recently switched over to a multicoin pool and notice it switches from one coin to another quite often.  I think I'm noticing that my GPUs are cooling and then heating up with each coin switch - I'm guessing it would have to stop hashing momentarily while it gets its bearing with the new coin.  Is this how its supposed to work?  Wouldn't this kill your efficiency and put startup wear and tear on your gpus?

Also, could someone recommend a trustworthy Dogecoin pool?

Do you use --no-submit-stale? Don't use it, might help.
