If I could distill all lengthy arguments down to one thing it would be this (and I believe any dedicated reading of the threads posted won't reveal alternate patterns, they are 100% relevant to this thread)
-cycles do predictable things in every setting, and at no time do they do unpredictable things-
so when bottle bac is purchased and used, its for specific times where not using it causes death in examples we can look up as web posts.
to use it outside of those events is to ascribe to the notion that cycles can do unpredictable things, and that's just exactly what they want us thinking and its 100% not true, in any case. cycles always behave predictably once we know the arrangement at hand. its so precise that we now for years have been cycling up totally dry rock systems using zero testing at all, merely timelining (as any common 80 year old cycle chart shows on the time axis)
*because cycles are so predictable after day 10-12 submersion, no cycling chart in history has an ammonia line that rises back up after it drops, on about day ten. search one out to see the pattern... no matter the website, all cycle charts are the same timeline that's a neat detail nobody discusses in cycling debates.
that water bacteria may unadapt, and be unpredictable in water, is a very 2000's+ training notion I can assure anyone of that. right when bac sales hit bigtime the lie took off.
