This document has been written in preparation for the instrument review of SPB/SFX scheduled for 15–16 March 2022. This will be the first instrument review conducted at European XFEL, as SPB/SFX was the first instrument (alongside FXE) to come online and perform user experiments at the European XFEL in September 2017. Since then, 36 experiments (as of December 2021) have been performed (of which 17 SFX and 4 SPI experiments used the standardized configurations). A total of 19 user-driven experiments have been published (so far) and more are in various stages of preparation. Of these 19 published articles, all present data collected using MHz repetition rates; 11 are SFX, 3 are SPI, and 5 present time-resolved data.
