What is the range of sentence for a defendant convicted of assault with intent to pervert the course of justice?

The court exercised its discretion under People v. Romero (1996) 13 Cal.4th 497 and dismissed two of defendant's strike priors based on remoteness. The court sentenced defendant on count 1 to six years, doubled to 12 based on the third strike prior; the upper term of three years doubled to six on count 2, which the court stayed pursuant to subdivision (a) of section 654; and, as relevant here, to consecutive eight years for each of defendant's eight prison priors, for a total term of 20 years.
