(26.5 fluctuating and 66 Hz)
16:30:34  B1p viewport (large 115-120 Hz,200, 322 and many)
(26.5 Hz and 20-30 Hz keeps fluctuating since we are around SDB1\2)
16:33:40 glitch
16:34:57 Hartman on flange in proximity of viewport (only a little 66 Hz)
16:41:00 Hartmann viewport (66 breathes a little)
16:43:40 B5 flange (similar to effect seen on B1 
flange more, effect above 400 Hz seems more 
intense, also 101 Hz,190 Hz)
