According to extender instructions, I thought you were suppose to wear your extender past your BPEL to gain. During the break in period, you wear it below BPEL for about 40 hours. After that, you are suppose to wear it past BPEL. Has anyone gained wearing their extender below BPEL for an long period of time like 1000 hours? I would be curious to know because it is much more comfortable with less tension.
