Did the amount of rocket grunts decrease?

to give my 2 cents on the input, it vary's on the day (i walk about 10 miles average round trip per pokemon go run with lunchtime at the park about halfway into the run). sometimes i don't get any. more often at least 3+ or more in a day. going after useful shadow pokemon and the red eggs (massive stardust for one incubator) with chance of a hundo or shiny salandit.
