Trying to read between the lines of this incredibly weird post, it would appear
the writer is suffering from the illusion that "fractional" airspace altitudes
in a given segment are indicated both for the charted (Class B) airspace and
for the underlying (Class E).

Even a very quick glance at the chart will show that airspace limits are given
as one number over another, separated by a horizontal line. The top number is
the upper limit, the bottom is the lower, in units of 100 feet. Since this
vertical positioning is not technically possible in running text, I used a
slash in place of the horizontal line. Nothing weird about that.

Readers should be advised of the fact that this
expert, offering his "presumptions" may never have seen a sectional chart, and
certainly has never studied the subject - does not know how to read the chart.

I've seen lots of sectional charts and I've become pretty good at reading
them.

The original poster, writing for information or clarification, should be
advised that use or application of any information gleaned from this expert
could lead to hazardous in-flight conditions . . .

Examples?
