When i started my carb cycle i was about 10% according to cAlipers and have managed to get to 7.8%.. thats as low as ive gotten but have been on a 8month cut and my drive has decreased slightly cuz im tired and think my body needs a break..
I got stuck @10% with strait low carb and cycling them was the change i needed.. 6% is ambitious and depending on ur specific body could be hard to achieve.. Not impossible just hard

u could try the low carb i suggested and see how it goes first before complicating things with a carb cycle..
I am a big fan of the carb cycle after having done it and it is the only way i will go from here on out for cutting..
My "low" days were 50g (broccoli only), moderate days 150g, high day 300g..
Basically:
Low
Low
Low
High

I also did ud2.0 to get from 9% to 7.8% which is also a carb cycle.. Its more complicated and on refeed day (30hrs) i ate 1300g carbs..
300g seemed a lot to me before i tried this.. Now 300g doesnt seem that much..
I suggest u researching the carb cycle for urself..
