We did the braids back before they made any changes to the styles and they never used product/gel on the hair to do those styles. The only one we ever had them use product on was the bun based style, so the bun and the one with the colored clip on hairpieces.
So I can't see how there would be any change to the braids.
And honestly, the gel made the styling go fast, it let them smooth the hair in one step. I can't see how not using it is anything but slightly slower, not faster. But I suspect in all it has little difference in time. They FGIT are good, they have their steps pretty quick.
