There are many factors affecting ferrite measurement by ferritoscope.
1) Check the calibaration
2) Adopt the correct method of measurement
3) More often pple measure the ferrite on grinded/machined surface which shows high ferrite no exactly in a range what you land up in(12-14%).
There is a negligible variation in ferrite no and percent so up to 10 you can consider both as a same.
