Right, half life.

60 days clean (tested (-) at day 39), minor lapse, will be 20 days from that day until the test. So, 80 days, with one minor lapse.

Tested (-) at 50 ng 4 days after lapse with dil. tested (-) 10 days after lapse w/o any dil. on first void of day

Figuring 100 ng level after lapse, 10 days would put me at 50, another 10 days at 25, which will be when my test is. should be able to dil. below 20 with a minor dilution, don't you think FBR?

I have a private test scheduled for tomorrow at 20 ng.

anyway, the employer told me it is a "DOT" type test, and i called teh facility and they told me this employer tests at 50 ng. unless i am completely being bullshitted and they ninja me, i should be just fine even without dil. on the 50 ng.
