MM(Girls) should be aware of peepers. If you want to prevent peeping, you should know how it is worked. The following content is from the Internet, which do not represent my views and and Sister Xibai’s views. It is only to pass on information. I wish sisters be aware of it at anytime and keep yourself away from peeping perverts.
Let us assume the distance between the knees and the upper edge of the skirt is 4 cm, and the distance between the outside edge of the skirt and the private part is 12 cm. Then from one side, the target peeping area will form a right angled triangle ABC.
If the peeper’s eyes are in the extension line of BC, for example E, then he will see B. If we draw an extension line across E through BC and vertical to AC, then it’s easily to find that ABC and CDE are similar triangles.
In triangle ABC, the length of AB is 1/3 of the length of AC, so in triangle CDE, the length of DE should also be 1/3 of the length of DC. And because DC is the distance between the peeper’s eyes and skirt, so DE will be 53.3cm if we assume DC equals 1.6 m
But the distance between a 170 cm tall peeper’s eyes and the upper edge of the skirt will be 70 cm. In another words, he has to lower his head by 17 cm and move his ass 45 cm forward to achieve his goal.
Wherever you go, you will find beautiful ladies going up and down on the stairs. Looking at the white legs, perverts probably want to follow her closely and fantasize of seeing something beautiful. Many perverts will surely dream about that, but this has to be some rules and techniques. What inside the short skirts is approximately the same as the picture shows below.
Normally, the peeper wants to see the area of hemispheroid with 10 cm radius. But the skirt is tangent to the hemispheroid and has a length of 15 cm from the center of the hemispheroid, which aptly shield the peeper’s vision.
From the picture above, the triangle OPQ and triangle ORQ is congruent. If we draw an extension line of QR and make another triangle TSQ, then we can calculate that its height is 8.3 cm and the height is 0.415 times of the bottom.
So if the peeper wants to see the private part inside the skirt, he should at least make the angle of elevation more than angle TQS, which will make the height 0.415 times the bottom.
Then we should discuss the issue of triangle AEQ. Assume the height of the eyes of the peeper (170 cm tall) is 160 cm, and the height of the edge of the skirt is 80 cm. Since the height of the eyes and the height of the skirt have a difference of 80 cm, so the difference (section of line) between the edge of the skirt and the peeper’s eyes is 80 cm less than the difference (section of line CD) of the stairs.
So Right angle triangle AEQ’s height and bottom can be shown by the two formulas below:
Height: AE = 20* number of stairs – 80
Bottom: QA= 25*( number of stairs – 1)
The height and the bottom should satisfy this formula: AE ≥ OA * 0.415
Here is a list of different stairs:
│number of stairs│ １ │ ２ │ ３ │４ │ ５ │ ６ ＞│ ７ │ ８ │
│AE │ -60 │ -40│ -20 │０│ 20 │ 40 │ ＞ 60 │ 80 │
│QA │ ０ │ 25 │ 50 │75│ 100 │ 125 │ ＞ 150 │ 175 │
│ratio │ ＊ │ -1.6 │ -0.4│０│ 0.2 │ 0.32│ ＞ 0.4 │0.457│
If AE is below zero, it means that the skirt is under the eyes. So when the difference of the stairs is less than 4, the peeper cannot see the private part. But when it comes to 5 or 6, the private part can almost be seen. When the difference is 8, the barrier is removed.
Of course, the wider the difference, the wider the vision, But do remember, what you see is less and less.
