I love that project, but it seems like it could use a refresh. For example, it currently still complains if the query cache is turned off...but Mysql does that on purpose, and will remove it entirely soon. Last time I used it, it also seemed like it was still straddling suggestions between MyISAM and InnoDB. It seems safe enough at this point to have the tool strongly suggest converting MyISAM tables and focusing solely on newer storage backends.
