Is there any reason why a patio should have a gradient of 1:10 instead of (AIUI) the more usual 1:50 to 1:100?

My mistake. My new patio is 1:60.
Topography?
The message from "Grumps" contains these words:
You live in a monsoon area? Or perhaps someone was too idle to dig it all out properly?
No, my brain didn't work when I was calculating the gradient of the finished patio. I measured the width in cm and divided by the drop in mm. The actual gradient is 1:60.
If I remember correctly the bubble on a good level will give you the slope. When the bubble is on one of the lines it is 1:400.
I've got a 6 ft level (actually 70 inches) that has two pairs of lines on each bubble. The inner pair are just a tad over the meniscus giving an extremely accurate reading. The outer pair show a slope the thickness of just under 7/8" (actually 3 x 2p; 4 x 10p and 4 x 1p coins.)
That's about 22mm in 1780mm. What's that? 1:81? That's an hell of a slope. I wonder where I got the 1:400 from?
As a rough comparison: The river Severn has an o/a slope of 620 metres (what's that in English?) in 220 miles.
Bloody hell! I wonder how wales is still there with a slope of 670 in
40 miles.Where is my TV guide?...
