Keeping a blog is also a good way to keep track of your logs and certain hand situations that happened to you and you wish to reflex upon.
Still observing the same log, the next hand in East 2 (dealer turn) is:
Dora:
You discarded again

. In this case, I -do- think it is correct, as this hand is different from the last one. Here, it's plenty possible to aim for hon itsu, and it doesn't look like that 9m is a useful tile at all as there are other candidates. Hon itsu also becomes stronger because we want to somewhat use that dora. However, it does not mean it's the only possibility out there.
Second draw:
I don't think the

you discarded here is quite right. I understand the feeling of "I have already decided on Hon Itsu, so now I will cut all other irrelevant tiles starting from the middle ones, to the edges." But this is not a very intelligent choice. First of all, once you draw

there is a good chance to win on your dealer turn with pinfu or a concealed reach (also, in case you drew another East, it doesn't hurt to have a completed group). Second of all, it's not like

is that much more dangerous than

. With such a little difference, I'd recommend discarding the 1m you just drew. Of course we're considering hon itsu, but there is also a discard order and a time for every thing. You kept a lone 8m by the fifth turn, too, which makes me only wonder why you had room in your hand for it, when you didn't for 9m or 2p. The sum of those little risks or mistakes or just playing without much deeper consideration can later result into little catastrophes, so make sure there is a good reason for every discard.
Eight draw:
(pon

) (pon

)
No

out there, no

s out there either, two

s are already discarded. you discard

from your hand for a 8s wait.
Hm... I'm not too sure about the effectiveness on that one. If you speak of position alone, it does look like it's "easier" to come out, but if you consider evolution for your hand's wait as well as not making others too suspicious of that souzu area, I'd recommend tsumogiri'ing this tile. The only tile that could possibly improve your wait is drawing

and there are already two of them out there.
Then, the person to your left discarded

(which would have been your winning tile) , you pon'd it and discarded

, making a tanki wait on the last 9s.
...Akagi? I would highly suggest against decreasing the amount of winning tiles like that, and making "psychological"(?) attacks on your opponents like that. The reasons are, first of all, it's not like the last 9s is 100% certain to come out looking at your calls and discards. If someone is 100% betaori, then it won't come out. Also, there is a pretty good chance it can end up in the dead wall, and your chances to draw this tile are minimal. Also, your opponents will feel like they're taken for fools if they happen to deal in like that (or they will feel like they're dealing into a fool, too) and they won't feel really good if you win the hand with that, and you won't feel good if you don't win the hand either, because if you played "logically" who knows what would have happened. When you try to pull stuff like that, I feel like the whole table suffers a great loss no matter the outcome, because the game itself gets degraded. No, I'm not saying you should always go for the wait with the highest number of winning tiles (though I'd love to say that!), sometimes it's important to choose waits which are "deyasui" or "easy to come out." That's the whole point why we love making tanki waits on honors for Seven Pairs, but I just don't think this table situation made it a very smart plan. Especially because this is a huge hand you don't want to let slip away, you should play it more logically.
Still, the mahjong Gods love you and decided to put the last 9s on your drawing turn. If they love you every game, you probably don't need the theory.
