Limits, who needs limits?
Not sure what you are refering to, but as we know the engine will attemt 3 autostarts on the ground before it gives up so that in turn becomes a defacto limitation. Also recall that if an engine flames out in flight the autostart function will run continuously without regard for limits. As far as the TOGA, I'm assuming you mean how long for TO thrust? Some engines are spec'd at 10 minutes and you can buy more time....for more dollars on most engines, maybe another 5 minutes if my memory serves me.
Not sure that I have addressed your question for forgive me if my answers do not apply to the question. You are correct regarding information that Boeing simply feels unworthy of your consideration as they have glossed over a lot of information that was previously sacred on other Boeings as well as other transports in general.
