Yes, it is correct. according to the new system to combat cheating, each time the ratings of a contest is calculated, the cases of cheating in the previous contest are also considered so ratings of both contests are re-calculated. This is done to reduce time taken to calculate new ratings as it takes time to report all the cheating cases of the previous month. In short cheating cases of October will be considered while calculating ratings for November and first October will be recalculated considering cheating and then November will be calculated without cheating.
