The answer to this question requires you to keep a close eye on your book rank and jot down whenever it spikes but you see no physical sale in your Reports graph. It's the only way to spot borrows since they aren't tracked anywhere (dumb oversight imo).
If your mtd chart shows 152, that's 152 pages read, equal to (approx) 70¢ at current rates...it varies slightly month to month. You referring to it as KOLL rather than KU suggests perhaps you've not read the help pages or the information under the KDP Select tab at the top of the page. Reading them would probably answer most of your questions and help clear up any confusion you might have about KU/KOLL and other aspects of your Select enrollment.
KOLL is Kindle Online Lending Library, which in the glory days paid $2 per borrow. It's a privilege of Amazon Prime subscribers, who can borrow Kindle Select books and some others without subscribing to Kindle Unlimited. (One book per month.)
(Don't trust KDP to publish a print edition. Don't trust CreateSpace to publish an ebook. Each does one thing well and the other thing poorly.)
