What you did is put the test really behind you and just relaxed. Relaxing for that means you are more prepared mentally and physically but I think if I am not mistaken it better to do about three shorter static breath holds then go for the longest one on your forth. I think the walking apnea helped somewhat with this. Also the problem with statics out of water allot of people breath using their nose and don't even relieaze it. I suggest you pinch or use a nose clip when practicing so you know the conditions are more consistent. You have nice static times keep it up.
