Okay thanks Trux. Now, how's this for a breath-up pattern from 2 minutes to official top?

...been breathing about 1 to 2 ratio of inhale versus exhale (steady, controlled inhale, followed by steady, controlled exhale of about double the time of inhale), then carry one for the last two minutes before top time... then full, steady exhale (or 'purge') ...followed by slightly quicker maximum inhale for dive...

I'm just having trouble with my final breath - it sometimes feels I'm not getting maximum potential of air in the lungs! I think it also could be a relaxation thing where I'm tensing my lung muscles so they're not able to perform to their potential..
