Proposition 13 sets the assessed value of properties at the time of purchase (known as an acquisition value system), with a possible 2% annual assessment increase. As a result, properties of equal value can have a great amount of variation in their assessed value, even if they are next to each other.  The disparity grows when property prices appreciate by more than 2% a year. The Case-Shiller housing index shows prices in Los Angeles , San Diego , and San Francisco appreciated 170% from 1987 (the start of available data) to 2012 while the 2% cap only allowed a 67% increase in taxes on homes that were not sold during this 26-year period. 
cheers guys, the reason i ask is because im running it alongside 60mg ed of var which im running for 7 weeks and only have enough for 300mg prop ed for 5 weeks. i eat around 3000 calories a day. im 185lbs so i eat between 180-200g protein a day, i only get carbs from my oats in the morning around 10am and grilled chicken on wholemeal bread and protein/carb shakes between until about 4pm. i then move onto protein only shakes and have a lean piece of turkey/chicken/fish with greens around 7pm then another shake at about 10pm. any ideas on how much i can expect to gain??
In the early 20th century, Bertrand Russell gave a different complete axiomatization of propositional logic, considered on its own, in his 1906 paper "The Theory of Implication", and later, along with A. N. Whitehead, produced another axiomatization using disjunction and negation as primitives in the 1910 work Principia Mathematica . Proof of the possibility of defining all truth functional operators in virtue of a single binary operator was first published by American logician H. M. Sheffer in 1913, though C. S. Peirce (1839-1914) seems have discovered this decades earlier. In 1917, French logician Jean Nicod discovered that an axiomatization for propositional logic using the Sheffer stroke involving only a single axiom schema and single inference rule was possible.
