Saturation breakpoint workaround?

From Fallen London Wiki

Action purge is not allowed on comment pages.

According to the announcement post:

"Saturation has a few different breakpoints.

-For the first 400 echos or so, your sales at the Rat Market will get the full Rat Market markup.

-After that, for another 1000 echos or so, your sales will continue to get a markup, though a lesser one.

-After that, you will still be able to sell at the Rat Market. You won’t get a markup, but you’ll be able to gain Rat-Shillings to exchange for other resources or for items."


This is just my personal speculation, but I wonder if it's possible to still get the full markup for longer if you sell in bulk when you're near it. Like, when you're at 390E of saturation, and sell in bulk/sell an expensive item, would you keep the better rate for that last trade?
