The upshot of pushing film and under- or over-exposing prints was that sometimes I got some really underexposed prints back from the developer, with the graininess that you'd expect. This was all the more obvious because the negatives were small, so there wasn't any leeway for blowing up prints past 5x7.
Surprisingly, because slide film was less expensive and developing slides was less expensive too, I tended to shoot lots of slides back in college on my little Auto 110 and with my Weathermatic 110. The slides tended to come out beautiful, and evening slide shows in my co-op among my artsy housemates tended to get lots of surprise and compliments on what my tiny cameras could capture. Kodachrome was amazing; I miss it dearly.
I didn't answer your question looking for your approval or disapproval. I simply shared my experience from decades ago. Experience later in my career, working with one of Kodak's leading color scientists 25 years ago taught me that sometimes Kodak went to amazing lengths to do things right, and sometimes they cheated on aspects of film design, chemistry, developing, and printing that they calculated wouldn't grossly affect the outcome of the customer's use of their cameras, films, or development services. However, sometimes they miscalculated badly. For example, the color scientist I worked with was tangentially associated with the fiasco that was the Kodak Disc camera system. He admitted that the idea to save money on film costs by going to tiny negatives was wholly triggered by bean counters, and Kodak product managers erred by not listening to poor focus group feedback and launching the system anyway. Nobody collects Disc cameras or film for a reason... they suck. 110 sucked a little too, but the convenience of having a camera that could fit in your pocket was alluring. There are gadgeteers like me who really enjoyed tiny cameras even if they made tiny prints. Check out the Minox enthusiasts for an even more extreme example. If you don't want to work with the limitations of 110 film, the modern dearth of 110 developers, and the crappy quality of modern 110 films, then feel free to go back to 35mm. Nobody is holding you against your will in this 110 thread.
