How often should I use my flutter valve?

I'm curious to know, how frequently should I be incorporating the use of my flutter valve into my practice or routine? Is there a recommended number of times per day or week that I should aim for in order to see optimal benefits or improvement? Additionally, are there any specific scenarios or situations where using the flutter valve might be particularly advantageous or where it could potentially have a more pronounced effect? I'd appreciate any insights or guidance you could offer on this topic.
