How closely they keep to their promise is loosely based on availability of Training Staff, which isn't always too good, and how loud you shout if they appear to be by-passing you, ( which can be purely due to losing the plot on their part). However they do need your ass in that left seat, so hey, give it a go if you have read / understood all the plusses and minuses well publicised here.There are however plenty guys inside with the pre-requisite experience, and, once they have got you, and you are in, your voice will be no louder than theirs, so don't expect miracles.
