What follows are my opinions of the game I believe Zodiac was playing. I believe the real Zodiac used the Ted Kaczynski name. I believe it all begins with how closely ZYNSKI and ZODIAC match up. The middle of Z(ODIA)C, those 4 are all EXACTLY TEN LESS than the middle of Z(YNSK)I.
GEMINI ZODIAC is found in a (0,10,20,30) Caesar shift from KACZYNSKI, and Kaczynski's sign was Gemini:
KAC*YNS=GEM*INI (-30,+30,+10,+10,0,-10)
ZYNSKI=ZODIAC (0,-10,-10,-10,-10,+20)
The Zodiac signs himself with his 12 pointed Zodiac symbol which can visually interpreted as a zodiac circle from astrology, if I'm not mistaken, the twelve signs are put into a circle each representing 30 degrees, but I may have to brush up on that a bit. So, in using (0,10,20,30) that can be put on the 4 points of the Zodiac symbol. It is my opinion that well before Zodiac struck on 12/20/68, he had the game he intended to play worked out. Here's what I think he did:
He took 6 signs of the zodiac and added their numbers-for-letters to the word ZODIAC's numbers-for-letters.
(Numbers-for-letters are just a letter's number position in the alphabet. For example Z(26)O(15)D(4)I(9(A(1)C(3)=26+15+4+9+1+3=58(ZODIAC=58)
LEO(32)+ZODIAC(58)=90
LIBRA(42)+ZODIAC(58)=100
ARIES(52)+ZODIAC(58)=110
GEMINI(57)+ZODIAC(58)=115
CAPRICORN(97)+ZODIAC(58)=155
AQUARIUS(107)+ZODIAC(58)=165
These are the ONLY SIX signs that when adding ZODIAC(58) to them will be a multiple of FIVE result. The reason for this I believe is that because when you mark these numbers(90,100,110,115,155,165) to the points they will fall on on a multiple of FIVE Zodiac symbol, in other words 0-60, the points they fall on are 6,7,8,9,10,11.(You will have to go around the circle once(clock 60) to get 90,100,110,115) and twice(clock 120) to get 155,165) That is an amazingly aberrational working out of numbers because then when you line up the points thru the center of the circle to their opposite counterpart, those are all unmarked points and so all of the circle's points are all lined up, or in other words you might say the circle is completed. So, in concert with this, I believe Zodiac intentionally struck on(or otherwise alluded to) dates that when added up would mimic this result of a complete circle.
12/20/68=100
7/4/69=80
9/27/69=105
10/11/69=90
3/22/70=95 (potential victim escaped)
6/19/70=95
9/6/70=85
I think, ideally, Zodiac would have liked to match the exact points on a multiple of five Zodiac symbol as the SIX SIGNS points. In other words, (90,95,100,105,110,115) would exactly match the points of those SIX SIGNS(6,7,8,9,10,11) on a multiple of five Zodiac symbol. However 115 is not possible as a date, not in the years 68,69, or 70. (12/31/70=113). (85 thru 110) is possible but only leaves a very few dates for 110. So, I believe Zodiac decided to mimic the SIX SIGN complete circle result by using(80-85-90-95-100-105) because just like the SIX SIGNS result, when lines are drawn thru the center, the circle is complete. In other words, as long as you have 6 points in a row, their unmarked counterparts will line up thru the center.
In my opinion, this guy, Zodiac, is showing off in his abilities to put this all together. It's like he's punning with numbers.
To go along with this, a continuation of the zodiac circle and numbers, Zodiac, I believe, was mindful of the numbers-for-letters in the locations he struck in. I believe that well before he struck on 12/20/68, he had figured out that in numbers-for-letters:
NAPA(32)+ZODIAC(58)=90
VALLEJO(77)+ZODIAC(58)=135 (135X2)=270
SAN FRANCISCO(122)+ZODIAC(58)=180
So those(90,180,270) are POINTS on a(zodiac) circle. So I believe he intentionally mapped out his locations by numbers-for-letters and he knew he had to stike TWICE in Vallejo for the 270 result. With SIX signs and SIX dates and with acting TWICE in Vallejo to get the 270 result I believe the math it shows is that Zodiac was after a 90-180-270-360 result. In other words:
1. 90 NAPA
2. 180 ?(Lake Tahoe Areas)
3. 135 Vallejo
4. 135 Vallejo (Vallejo=270)
5. 180 San Francisco
6. 180 San Francisco (San Francisco=360)
By this you would have:
NAPA=90
LAKE TAHOE AREAS=180
VALLEJO=270
SAN FRANCISCO=360
