A: If you compare from a cost per query standpoint, then yes you will feel T2 is the best. But also note that its more about the extra flexibility that T3 offers, instead of the cost. If your usage is really high, mostly you would prefer to have the flexibility of the service to remain active all throughout the month. If that is your priority the T3 model is best fit for you.

From our standpoint, our data modelling suggests us that T3 users will be more expensive on an overall basis vs T2 users. Given additional cloud costs, additional usage expectations, etc. We see a skew in the usage distribution which shows that some extreme power users (mainly in T3 category of usage), use us way more than the T2 ones. And given the pricing of our plans is on a breakeven basis (we designed it so that it just breaks even and there is no margin), hence the cost per credit is slightly higher than the T2 plan. Its not like a buck purchase here, given the data model suggests that the usage of T3 purchaser too is relatively more higher than a T2 one (after accounting for the credit disparity). We need to do this math very accurately in order to offer a sustainable lifetime deal.
