  • Hi all, I’m using Frontier X2 since more than two months and it is very good! I’m training almost every day (I did about 70 records) and the percentage of Other Rhythm is always between 0% and 1.8% max. Is it something I need to be concern on? Thanks! Cheers

    • maybe it relates to the record time, you can ask your doctor

    • Only THAT small! I think you’re one of the lucky ones & should be very pleased with that result. 😁
