This is 100% correct! octane numbers are a ratio making 100 the highest ratio, when petrol is concerned, higher octane off road fuels are chemically blended fuels, pay no attention to any of that with what your trying to accomplish.
Your mix should give you about 94 octane which is above the 93 you are shooting for to run the increase in boost. With cooler temperatures this wont matter much, but in hotter months you probably may want to make sure you do this mix.
In Vegas 100 is $5 a gallon I think, not too bad if your mixing.
