i don't know, but i'll let you know if it works for me.
i haven't been doing any fast pulls, but i have been doing litvinovs with double KB swings.
i DLed 235lbs, or 1.59x BW, in the first week of June. i'm trying to get to a 600lb CFT by the end of the year, so in about another month or two i'm going to start DLing again. hopefully there'll be a significant change in my 5RM at that time. i'm going to test my CFT near the end of december.
