new blipper

Molly taking a photo of her mum in the park.

Have a bit of a dilemma concerning the number of blips me and K have taken. According to blipfoto this will be my 199th picture. Despite me and K starting on the same day, neither of us missing a day, blipping our 100th photo on the same day, K blipped her 200th blip today. We can't figure it out. Same amount of photos, no missed days and yet we've become a day apart. Any ideas?
