Bearing in mind Apple sells 8 different form factors of iPhone, 10% sales seems viable. They can't all be the best seller. Even if you only count 'models' and not the different sized versions there are still 5 of them. In that context 10% of sales seems enough to justify doing a mini or SE version every other year at least.
