Flink's timetable guide for completing the Event Gacha:

->Open Spoiler<-

Day	Number of Reset	(coin cost)	Current Gacha completion
Tuesday 15	1	70	80%
Wednesday 16	2	105	70%
Thursday 17	3	140	50%
Friday 18	4	175	10%
Saturday 19	4	175	60%
Sunday 20	5	210	10%
Monday 21	5	210	50%
Tuesday 22	5	210	90%
Wednesday 23	6	245	30%
Thursday 24	6	245	70%
Friday 25	7	280	10%
Saturday 26	7	280	40%
Sunday 27	7	280	70%
Monday 28	7	280	100%

The most important part is the 2nd column. It gives you the number of reset you should have done at the end of the day.
The coin cost is a good indication to know how many reset you have done.
If you are not in the corresponding Gacha, it means that you are not fast enough, and it will be difficult to get the rewards you want.

The 4th column is for those who want to get all the rewards ... or those who are not lucky.

For exemple:
At the end of Tuesday 22, you shoud have done AT LEAST 5 resets. If you did more, its OK, but if you are still in this gacha you should be close to finish it.
Otherwise, pray the RNGod Moarsi.

With Monotropastrum Humile confirmed for the next event, guess who's finally in the gacha!

->Open Spoiler<-

Lycoris: #1. (Four allies' attack power +18%), #2. (Evasion).
Epidendrum: #1. (x1.5 Self skill trigger on 1st turn), #2. (Evasion).
Snapdragon: #1. (Three allies' attack power +15%), #2. (x2 Def-powered counterattack, 80% chance).
Monotropastrum: #1. (Three allies' attack power +10%), #2. (Evasion).

If I recall correctly, somebody was really looking forward to Lycoris when the game started, so now's that time!
