What is the "10% burn" on the Stride LSD daily report?

10% Burn on @stride_zone LSD exchange rates spreadsheet 10% below the current exchange rate.

For example, if you buy $stATOM at 1.22601 (just above that largish buy-order on @TeamKujira FIN)

...then burn that $stATOM on @stride_zone, you would gain 152% on your $ATOM (annualized).
