My progress and plateau

Hello,
Started with a x4 labs extender at the end of April 2017 with a BPEL of 6.125 MEG of 6.00. Three months later about 20 days into July I was measuring BPEL 7.00 MEG 6.00, and took the rest of the month off. Returned to PE at the beginning of August and have averaged 3 hours 10 minutes of stretching per night and also added clamping to my routine and four weeks into August i am measuring BPEL 7.00 MEG 6.25, additionally I have regained my left hand curve which had all but straightened out during my first 3 months.
So as my progress in length has stopped the clamping routine is helping my girth get really big and created the curve as far as I can tell. I would like to get my gains going again in the length department as I have a long term goal of BPEL 8.50 and MEG of 7.25. Short term goal of BPEL 7.625, MEG 6.750 Any advise would be welcome.
Thanks,
P.VEE
