I had a hard time answering this question because I do not know how much security levels improve security in quantitative terms.
Is this right?
e.g. (Hashspace increment)
- 81 trits =>
27^81 ^1 (low security)
- 162 trits =>
27^81 ^2 (medium security)
- 243 trits =>
27^81 ^3 (high security)

e.g. (Attempts increment)
- 81 trits =>
1* 27^81 attempts (low security)
- 162 trits =>
2* 27^81 attempts (medium security)
//Two times more attempts//Two times more attempts? - 243 trits =>
3* 27^81 attempts (high security)
