Thanks for the advice @Morax I really appreciate it (and the pictures help me see as well). I didn't even realise how much reclaim there was until you pointed it out, and as you said the maa placement was pretty bad.
Day 6 (May 2nd): I think I'm starting to get better although today's game (Replay 16945374) did not end well. It was a mapgen game on an interesting water map, so it gave me some experience with an area I need more of. After the game, I reviewed the replay and then ran into Swkoll, who watched the replay and mentioned things I had missed completely. I'll try and compare what our different thoughts were to illustrate the difference in mindset.
Things were going well at first, I had secured the naval reclaim due to having more mass in frigates, but I lost (suicided) air and my comm was killed by torps. I need to strike a balance between using my acu to reclaim and keeping it safe. I'm getting better at spamming less factories than I really need but I still overbuilt on frigates and torps. I've often had trouble recognizing when I have more than enough navy to win, usually it is the opposite, so in this game I wound up with more than I needed before I realised. This game will help me figure out when I have made too much of something even if it isn't causing me to stall.
I also was late on getting some of the reclaim and let my opponent take some from my side. I also really underestimated how much power T2 and T3 air would use. I think mass stalling for a while blinded me to having not enough energy. As soon as I was finally able to use the mass I didn't have the energy.
Swkoll mainly highlighted bad trades with navy, idle units/ACU, missed reclaim, and spending mass andpower on stuff I didn't need (extra factories, T3 before I could spend it, too many mex at the same time, etc). Another thing Swkoll mentioned was adding in T1 bombers into my air queue. This would give me bombers before I need them, which would be helpful on larger maps in saving apm and attention, especially against Zthuees. He gave a lot of good advice, too much to give more than a brief summary of. He also predicted how the game would go as it went. A big difference is that Swkoll doesn't see my biases or rationalising so he stays completely objective, and is also much more experienced. Going forward I will try to view my games as an outsider, while also figuring out why I do the things I do. As an example, I think I realised why I miss so much reclaim in certain games. Aside from ignoring many of the smaller rocks, I also am used to all the mass being gone after the first few minutes, so I stop looking for it and trying to go for it except where there are fights.
There's a new map pool out, and with it new adventures! Also noticed a lot of people like Femboy, Techhousenoob, Grimplex and Harzer making useful ladder content. I'm still planning to train with Tagada as well. so the next few weeks will be quite eventful.
