Obsidian break times in ticks

<efficiency level>: <break time>, 2x = <break time for 2 blocks in a row>

No haste:
5: 46, 2x = 96
4: 62 2x = 128
3: 85 2x = 174
2: 117 2x = 238
1: 152 2x = 308
0: 189 2x = 382

Haste II:
5: 33 2x = 72
4: 44 2x = 92
3: 61 2x = 126
2: 84 2x = 172
1: 109 2x = 222
0: 135 2x = 274


1. There is a 4 tick delay between breaks when breaking 2 obsidian blocks in a row
1. When using eff5 & haste 2, the delay is 6 ticks
