Doesn't this scoring method encourage pool hopping?

I mean, what is to stop someone for creating a tool to mine this pool for only the first 15mins or so of each new round and then jump over to another pool, a PPS perhaps.

Lets say your payout average is .25 a block on Slush and .20/hr on a PPS. Lets also say that out of 20 rounds, Slush has 5 10min blocks and 15 2hr blocks . The hopper spends 4hrs or so on the pool and gets full payment for 5 blocks in addition to a consistent rate from their PPS pool in between.

Over the 30 hours:
The hopper gets 1.25 from Slush, + 5.2 from their PPS. Earning 6.47 BTC.
Loyal slush miners get full payment for 20 blocks. Earning 5 BTC.

If slush had 20 rounds all 2+ hours:
The hopper would get nothing for their 5 hours, and they only spend 5 hours even if some of those rounds are 4+ hours, but the other 35+ hours spent on a PPS they earn at least 7 BTC.
Loyal miners would earn 5 BTC over the 40+ hours.

You need to read more of this thread to understand the scoring. The scores are weighted towards the end of the round to stop this. A hopper doing what you describe would get little or nothing from most rounds.

What part did I not understand? They get full pmt for the short rounds they were part of entirely and nothing for the long rounds they left on.
