I do not know if it is normal but you can use computercraft to exceed the limit (98) from the injection rate.

In the statistic of the reactor stands inj-rate of 354 35.4 mrf
But there are about 1.56grf

But with inj-rate 512 only 51.2 mrf

And also that the number can be 7 or 99 normally 6, 8, 10, ...

Sry translated with google

Yes, this is normal :)
