A lot of time and effort is invested in making decompression schedules as safe as possible however, enough testing always shows a failure rate. That is because these tables are simple mathematical models with some empirical fine tuning to try to reduce the bend rate to an acceptable level for the target audience (viz; a bend rate of 5% is OK for the Navy, they mostly have recompression facilities shipboard whereas I personally would use a table with a lower bend rate than that). Decompression illness is a complex process which is only inititiated by bubbles. Every dive involves some venous bubble formation (Eckenhoff et al 1990) therefore every dive has a liklihood of DCI. Dive often enough and you are going to get bent. Not your fault, just that the models used to create decompression schedules are simplistic.
