Radio airplay is measured on a 7 day rolling chart. Each day they take out the airplay gain from 7 days before, starting from day 8, but still adding the daily update. The total airplay gain that day is from combining those two factors.
For ex, if the song gains 13000 on the first day and 3000 gain for the rest of the days
Day 1: +13.000
Day 2: 16.000 (+3000)
Day 3: 19.000 (+3000)
Day 4: 22.000 (+3000)
Day 5: 25.000 (+3000)
Day 6: 28.000 (+3000)
Day 7: 31.000 (+3000)
Day 8: 21.000 (-10.000) (3000 gain minus the 13.000 from day 1)
Day 9: 21.000 (+0.000) (3000 gain minus the 3.000 from day 2)
