Do you mean the per-block instruction limit? I wasn’t aware that deterministic time cycles would actually save the user some cycles.
No, what Claudio meant is that a message will be able to run across multiple rounds (on each round consuming up to the limit allowed for a single execution), therefore being able to run longer overall and not be limited by the single message limit. In fact, running a long computation will likely cost a bit more in total but the key is you’ll actually be able to do it. More details in the relevant thread.
