The data you have is only posted every 24 hours…
So "still glitching…" not correct…
Schumman is a measure of radio waves that (should be) consistent. Schumman found that the main wave had a frequency of 7.x hz and started his measures…Schumman stayed consistent at least until 11.11.18 with the PING heard round the world…
THIS is a way better site with more detail w/REAL TIME DATA…
BTW..if (your) frequency was increasing would that be measurable? If (all) of our frequencies were increasing would that be measurable? If the earths resonant frequency was also increasing would that be measurable?
Yeah…#itshabben
