It's a really good test animal for checking which epoch to use. When the lora is overtrained the tails start phasing around like crazy, and their fingers glitch as well. I used to use baby tigers, but found lemurs were a better indicator of a good model. If the lemur is active/reactive in the scene, you know things are good.

When testing across all the epochs there are many that will produce the correct likeness or style. But you want to find the epoch that consistently produces the style while also being flexible enough to produce weird conditions (lemurs) -- all while not glitching. If the lemur moves around in a way that physics behaves correctly and none of the limbs glitch, then you are in good territory. You want the strongest epoch that produces better behavior than the original. If you notice in my comparison images I feel like the original is being improved (not just applied style) by having my LoRA applied -- in fact, that's a requirement of my testing.
