The log skeleton miner (that is, the plugin called “Build Log Skeleton from Event Log”) in ProM 6.11 scores 98.3% on the PDC 2021 Data Set when the log skeleton is set to use 1% noise. When combined with the conversion to Petri nets (plugin called “Convert Log Skeleton to Petri Net”), which results in Petri nets instead of log skeletons, the score is 97.6%.
