What other factors determine whether a very busy ICO accepts your transaction?

Apart from gas.

Many ICOs sell out within seconds of the address becoming available, what other factors decide who gets in? Is it basically just luck?

In addition to gas, must also be taken gwei into account. Gwei is the price you are willing to pay for one unit of gas. In general, it is necessary to follow the recommendations of the company that conducts ICO.

ok, I meant apart from gas limit and gas price. Is there anything about the timing that will make a difference? Can you be too EARLY in a busy ico, like does timing depend on when blocks are finalised so that sometimes people who send funds slightly later end up being included faster than people who sent before?
