Forty linear feet is nothing, so blaming yourself over feed rate feels like a stretch. A shank snapping clean at the collet usually points to a worn collet or a bit that got dropped at some point, not your technique. I'd swap the collet first and see if the problem just goes away before you change how you cut.

Ten pages in one paste is wild to me. The model has to figure out what matters across that much text at once, so it just averages everything out and gives you mush. I tried it with a six page lease once and got a summary that missed the actual rent number, then did it page by page and it caught everything. Splitting it up really is the difference.

Wait, are the lids actually good on those though? Because I grabbed a few of the big ones for flour and sugar and the lids pop off if I look at them wrong. But the small ones on my spice shelf? Total game changer, I lined them all up and my husband asked when we got new cabinets. I also grabbed a couple of those little chalk labels from the same aisle and now my rice and beans look like they belong in a cooking show. For like four bucks total. I keep going back for more every time I'm near the store.
