The part I do agree on is bombarding them with proof. People think it's going to make things faster but that only pisses them off. Only send what is absolutely necessary, sending 500mb or a huge package of things is really just going to cause trouble and delay things. Or emailing them and harassing them over and over again is only going to make you get on their bad side.
Either way it won't make it faster as they all have a particular bring forward date but it does save time IF you truly feel they will ask you later on judging based on how strong your case was. Nikkah only, second marriages, no ruksati, shorter period of stay. These are the reasons people should consider sending ad doc. But ONLY what is necessary. Also, I don't suggest voluntarily sending your plan for upcoming functions or intentions ahead of time, that can become negative..wait until requested for things like that as that is dependent on which immigration officer you end up with.
