This should be cool. I think the individual biases and typing errors will tend to even out, unless there are systemic typing errors among forum members.

Here's a fairly large set of types from among my relatives, using the 3-letter code (sorry). If the sample is too large, just take the first line, I guess.

IEE, SEI, IEE, EIE, EII
LSE EII LSE LSE EII LSE
LSE EII LSE EIE
SLE LII ESI SLI SLE IEE LSE IEE ILI IEI
ILI ESI ILI ILI SEE
ESE SEI SEI SEI SLI
ESI SLI SLI SEE
