Critical chance boosts are applied multiplicatively. This means that when you have a weapon that has a base critical chance of 10%, increasing your critical chance by 100% will double the base critical chance, resulting in a 20% chance of a critical hit.

If you use both Point Strike and Critical Delay, you get a 198% increase to your critical hit chance. On a weapon with a base critical hit chance of 10%, your new critical hit chance is 10*(1+1.98) or 10*2.98 which is 29.8%.

On the infamous Soma, with its base critical hit chance of 30%, your new crit rate would be 30*2.98 which is 89.4%. That's really impressive, but not over 100%.

However, you can stick this pair of mods on the Synapse which sports a beefy 50% base crit rate. Increasing its critical hit chance by 198% will boost you all the way to a ludicrous 149% chance of a critical hit. By all accounts, this means that every tick will deal critical damage, but nothing more extraordinary will happen.

TL;DR Increasing your crit rate over 100% is a waste of mods, but you can only do this on a couple of weapons so don't worry about it too much.
