Not a major deal, but the $1 in $8 calculation is a bit off, since it doesn't take inflation into account. The math still holds for the most part.
Adjusting for inflation and rerunning the same calculations:
* $2,600 -> $2,902.47 -> 2011 median rent adjust to 2018 dollars
* $3650 - $2900 = $750 / month increase in rent.
* $750 / .69 = $1086 / month increase (pretax)
* $52000 -> Increased yearly burn for a 4 man startup.
* $208000 -> 4 year pre-tax burn
* $208000 * .69 = $143520 -> 4 year amount to land owners
* $500,000 -> $558,166.51 -> Average seed round in 2011 adjusted to 2018 dollars
* $2.1M - $558K = $1.5M -> Increase in venture funding
So $143K / $1500K goes to Landowners, which is $1 in $11, not $1 in $8, or 30% less than originally calculated.
