Does there exist any analogous result for site percolation? This is a sequel to the question: Proof and interpretation of the following percolation theory result for $n\times n$ square grid
In the paper: The Birth of the Infinite Cluster:Finite-Size Scaling in Percolation

Theorem 3.2 basically states that with probability going to $1$ as
  $n\rightarrow\infty$, the largest open cluster in an $n\times n$ box
  is of size $\theta(p)n^2$, $\theta(p)$ being the percolation
  probability (where $p>p_c$). Moreover, Theorem 3.1 part (iii) states that the expectation value of size of the second largest cluster is of sub linear order. 

This result is for bond percolation. However, does there exist any analogous result for site percolation?
 A: Concerning the relative size of the largest cluster $M_1$ and the second largest cluster $M_2$, for site percolation in an $n\times n$ lattice with site-occupation probability $p$, one has the scaling law 
$$\langle M_1/M_2\rangle = C_0 + C_1 (p-p_c)n^{1/\nu}+{\cal O}(p-p_c)^2$$
with critical exponent $\nu=4/3$ and percolation threshold $p_c=0.59$. The coefficients $C_0$ and $C_1$ depend on the boundary condition. 
See, for example, arXiv:1504.07712
The averages of $M_1$ and $M_2$ separately scale as 
$$\langle M_1\rangle=n^{2-\beta/\nu}[a_0+a_1(p-p_c)n^{1/\nu}+{\cal O}(p-p_c)^2],$$ 
$$\langle M_2\rangle=n^{2-\beta/\nu}[b_0+b_1(p-p_c)n^{1/\nu}+{\cal O}(p-p_c)^2],$$ 
with $\beta=5/36$. Hence the ratio of the averages, $\langle M_1\rangle/\langle M_2\rangle$, follows the same scaling law as the average $\langle M_1/M_2\rangle$ of the ratio, upon substitution of $C_0\mapsto a_0/b_0$, $C_1\mapsto (a_1 b_0-a_0 b_1)/b_0^2$.
So I would conclude that this scaling for site percolation differs from the $n^2$ scaling for bond percolation.
