What are the odds of a perfect echo in Wuthering Waves?
5 chosen substats: 1 in 1,287. All 5 at top roll: about 1 in 57.9B (0.0000000017%).
If you could roll one every single second without stopping, you'd expect a hit after about 1,800 years.
Any rolls
Only 1 of the 1,287 possible sets of 5 substat types matches.
The odds are the same for any 5 stats.

1 Tacet Field run (60 Waveplates): about 24,155 Echo EXP (4.8 Premium Tubes) and 20 Premium Tuners. 240 Waveplates per day.
One run drops tubes and Tuners together, so the scarcer one sets the runs. Echo drops are not counted.
Money: a 60-Waveplate refill costs 60 Astrite (the first 2 each day). 1 pull = 160 Astrite. At the $99.99 Lunite pack, 1 Astrite ≈ $0.0124, 60 Waveplates ≈ $0.74, and 1 pull ≈ $1.98.
Other ways to buy Waveplates: Sage's Solvent Aid, $4.99 for 7 Crystal Solvent, is $0.71 per 60 when the shop offers it. The Lunite Subscription, $4.99 for 3,000 Astrite, is $0.10 per 60, for up to 3,000 Astrite a month.
