I calculated what happens if there is no Gridcoin team requirement exists.

Method

Export stats/host.gz from projects, unpacked, then do summ for all hosts:

$ grep '' numberfields | grep -o -e '[0-9.]\+' | awk '{s+=$1} END {printf "%.0f\n", s}'
18802352

Then compared to Gridcoin team stats.
No data for enigma, einstein, wcg.

Results

Greens are competitiveness rise less than in half
Yellow less than in fourth
Red is more than fourth

Conclusion

• LHC, Rosetta and SETI become VERY competitive (rewards will be 10x lower)
• Asteriods, Universe, Collatz, GPUGRID, Milkyway, PrimeGrid become more competitive.
• Almost nothing changes to latinsquares, TN-grid, yafu and VGTU.
