Based on the existing answers and the question, it appears that Temple router is not currently able to find the optimal route when it comes to accessing liquidity pools, as it is not yet integrated with every pool on every supported dex. This is because the integration process is a manual one and the team is currently focusing on adding the more popular pools first. However, it does appear that Temple router is able to do much better than QUIPU when it comes to finding the optimal route, even though the swap is all on QUIPU. The easiest way to integrate plenty would be to integrate the plenty router, rather than having to go through separate liquidity pools. Unfortunately, it is not currently possible to access plenty, so it is not possible to check why Temple router did not find the plenty route.
