You're welcome. I'm glad my log is a source of inspiration. My rate of progress has been a lot slower than the SS ideal, but I'm still happy to be lifting weights that would have terrified me a few months ago. Start your own log - I'd be interesting in following your progress.
I'm not in a position to coach anyone based on my limited experience, but I do think that trying to get your form right is time well spent. I still have squat form issues after more than four months and think I might need some coaching to get this sorted out. I started at 50 kg at a lighter bodyweight, so I don't necessarily think that was too heavy, although it really depends on how hard it was for you at the time.
Squat is also the toughest lift for me. You're not that much shorter than me and I do feel that being fairly tall and slender gives me an anthropomorphic disadvantage with this lift. My head does indeed feel like it's going to explode on my heavier squat sets. I've also experienced a hugely reddened face and light-headedness after heavy sets. To me these are just a sign you're working hard. What's nice though it that on my current deload I'm not getting these feelings at 92.5 kg.
Deadlift was my favourite lift at the start as the weight kept shooting up rapidly. Unlike the other lifts, for me it feels like that even when the bar starts to feel heavy I can go quite a bit higher. For example, on my last workout my final warmup set of 110 kg felt very heavy, but I still sucessfully pulled 130 kg. My deadlift working sets feel very tough now and lead to the same sort of symptoms I described for squat earlier, but they're less intimidating than the squat as the bar is not trying to crush you into the floor.
I'm glad the kilos are helpful. One thing it took me a while to pick up on were that the common weights you see quoted are just multiples of 45 lb plates, which is approximately equal to 20 kg plates, although the US loads will be a little heavier.
i.e.
135 lb = 1 plate = about 60 kg
225 lb = 2 plates = about 100 kg
315 lb = 3 plates = about 140 kg
405 lb = 4 plates = about 180 kg
