retention basin and infiltration on site

I am a little confused: The reference guide states that average TSS removal of an infiltration basin is 75% (50-100%). However, from several comments and the sample uploaded I get the feeling that if you infiltrate all rainwater on site then 100% removal can be achieved. Can someone help with this issue? If using a basin that collects and infiltrates all rainwater, can you use the 100%?

I think 100% may be a bit of a stretch, you are enver going to filter out all the solids. But if you have a unique situation, by all means, justify it in your application and go for it.
