Every time we've ever enabled smart pricing, it's been by mistake. Pressing the wrong button inadvertently.
In each case (1 or maybe 2 times), we've had to accept bookings at about half our usual rate. I don't think smart pricing actually considers apples to apples market comparisons. It seems to just total everything booked, from 1 bed share homes to luxury palaces, averages it out, then that's the "smart" price. It seems to consistently average well below actual market rates.
So it occurs to me that if smart pricing actually gets you a better rate, then perhaps you're underpricing your offerings in the first place?
If so, is it that you're concerned that you won't get any bookings? Airbnb has the largest market reach on the planet. Just be patient. There's another guest in the queue, willing to pay your price. As long as you're reasonable about prices in the first place.
Being too "reasonable" is also just giving away money. Look at the competition carefully (for your class of product). I suspect many may be a bit pricier than you.
Also, it's been a rough couple of years. Any lower priced competition may not have been booked up yet. But as soon as they are, you'll bubble up to the top range of choices. At >your< price. Just be patient.

For ma y reasons, we're forced to have 2 listings, one for high season and one for low season. The pricing models need to be different. Airbnb doesn't have any facility to adjust pricing models on a seasonal basis.
