Response to pulling hp5 to iso 250

I used to use the old HP5 at an EI of 200. It worked very well in Perceptol. I used it one part water one part Perceptol for about 10%( I think!! 16 min;s at 20deg C) more than the published times. The same should hold true for HP5 Plus. The combination worked very well for flash photos taken at fashion shows.
