"beginners that do well in Rating Game goes through a period where they face a losing streak because the opponents study you enough to make a strategy to beat you."

That arguement is a valid one, but only partially in Issei's case. Issei has been a "wild card" from the very beginning. No matter who he faced, and what kind of strategy they came up with to counter him, Issei has always either powered through it (like when Sairaorg had his bishop strip to counter Issei's [Dress Break] and [Pailingual]), or pulled a secret move out of nowhere to turn the whole situation around (in his fights with Riser, Sona, Cao Cao, Euclid, etc.).

In fact, the only reason Dulio won the RG match was because Issei's team was just 1-2 seconds too late. The "Gabriel Strip-Show" and "Use Irina" plans were effective in taking the lead, but Issei revealed the [Crimson Destruction Dragonar] and [Dress Break-DxD] (and Elmenhilde drank Issei & Ravel's blood) which gave them the chance to score one more goal and win. But the timer ran out first.

Despite their strategies and preparations to deal with Issei and his team, Dulio's team was "saved by the bell/buzzer." That should make it very clear that Issei isn't someone you can completely prepare for.

And the dialog between Issei and Ravel foreshadows that Issei isn't done. He's still got more tricks to reveal. And not even the Gods can predict or prepare for what might happen.
