What do we know about the first occurrences of prime gaps? Are there any conjectures from which we can infer something about the first occurrences of prime gaps length $n$ and their distribution? I've made an interesting graph of these values to make this problem easier, with gauss's approximate of their size, $\log(p)$ on the $x$-axis and on the $y$-axis the proportional error, i.e. $\frac{g(p)}{\log(p)}$. A prime gap $g(p)$ is $p_{n+1} − p_n$. What on earth is going on with gaps with error from 25 to 30, why are some of these gaps starting so late, does this pattern continue somehow? I needn't say anything about the nature of the large 'line' but does anyone see the vertical 'wave' like pattern with the anomalistic bunch?

I hope this question doesn't come across as too wordy or vague but would really appreciate any general comment.
 A: Graham conjecture
We can determine a boundary for the first occurance of certain prime gaps if obeying one or more of the two conditions below. If both conditions are obeyed, then we determine that the first occurance of a prime gap is found following the condition which gives the lowest least bound.
condition 1 -symmetric condition for symmetric type gaps.
The first symmetric gap of length $2p_{n}$. It is between consecutive primes which are larger than $p_{n+2}^{2}$ and are equal to $k(\#p_{n+1}!) + p_{n}$ and $k(\#p_{n+1}!) - p_{n}$ such that k is the smallest natural number so that they are both larger than $p_{n+2}^{2}$.
Condition 2 - one directional condition for non symmetric gaps.
The first occurance of a non symmetric gap length $p_{n}-1$ is greater than $p_{n-1}^{2}$ and less than $k(\#p_{n-1}!) $where $k$ is the smallest natural number that doesn't produce a contradiction.
Like i said before, and to clarify; the lowest occurance of a gap, if both prerequisites are met - is the lowest boundary given by them. The lowest gap is either symmetric or not, i don't know how to determine this yet, but one if the two conditions will be correct if both prerequisites are satisfied.
