Well, I think there are some little things that should be changed in the bronze charts. One of them is the call with 32s in the chart "Actions against callers in front of you", with 3+ limpers. Maybe something like 54s would be more appropriate, because of the fact 32s can only hit very few straights, will be often at the bottom end, and can hit only 1 OESD on the flop. While a hand like 54s can hit more straights, and 3 different OESDs on flop, so it has much better playability IMO.
And maybe some suited gappers could be included instead, maybe J9s or T8s, even 97s would be worth more than 32s. Also, if there is a raise after I call, I'd feel much more comfortable calling one of those hands than 32s (which hardly would be getting the right odds).
And I also have a suggestion for a new chart, it would be like "Big Blind with callers and raisers in front of you". Let's say I'm holding AJo or KQo in the BB, some MP raises and 2 players call the raise. Now I'm getting 7.5:1 odds for my call, but according to the chart "Calling/Raising with raises and callers in front of you", I should fold my hand (which hardly is correct). In these cases it's clear I should call, but with hands like QTo or maybe K9s I'm not sure if calling or folding is more correct.
So it would be nice to have the calling ranges for the BB when you're getting nice odds and another advantage in that situation is that you're practically closing the preflop action (nobody is likely raising after you).
What do you think?
