i suspect speed research and quality research is reversed.
i got a lot of quality research on one dish and no speed research, but when challenging, my speed is very high but judges' scores are very low (comparing to the opponent which has about the same research level)
Number of ingredients matter more than research in battles. So if you use recipes with only 2 ingredients, you can create it much faster than a recipe with 10 ingredients. Number of ingredients are a multiplier for the score. So 10 ingredients would give 5 times as much points than 2 and it doesn't take 5 times as long to make it.
To people concerning about Zero Deaths achievement, while you are doing challenges, you wont have the galaxy even if you bought the IP upgrade (the right most column of IP upgrade doesnt work in challenges)
